----------------
-
-CHANGES IN CUPS v1.0.5
-
-	- The HP-GL/2 filter did not correctly set the pen color
-          for pens other than #1.
-	- The scheduler would only accept 26 simultaneous jobs
-          under some OS releases (mkstemp() limitation.)  It now
-          handles up to 2^32 simultaneous jobs.
-	- The PostScript filter loaded the printer's PPD file
-          twice.
-	- The PAM authentication code now uses pam_strerror() to
-          provide a textual error message in the error_log file.
-	- The scheduler now copies PPD and interface script
-          files instead of moving them; this fixes installations
-          with a separate requests directory.
-	- The PostScript RIP did not generate correct 6-color
-          output.
-	- Several filters were marking PPD options twice when
-          they didn't need to.
-	- The scheduler did not save the printer or class state
-          after an accept-jobs or reject-jobs operation.
-	- The cupsGetDefault() function now ignores the PRINTER
-          environment variable if it is set to "lp".
-	- New ippErrorString() function to get textual error
-          messages.
-	- Better error reporting in the System V commands.
-	- The lpadmin and lpstat commands always tried to
-          connect to the default server.
-	- The text filter didn't load the charset files from the
-          correct location.
-	- Wasn't sending a WWW-Authenticate: field to HTTP
-          clients when authentication was required.
-	- httpSeparate() didn't always set the default port
-          number for known methods.
-	- The HP-GL/2 filter now looks for "PSwidth,length"
-          instead of (the correct) "PSlength,width" as
-          documented by HP.  It appears that many major CAD
-          applications are broken and this change allows the
-          auto-rotation to work with them.
-	- The IPP "printer-resolution" option was not being
-          translated.
-	- The charset files did not include the Microsoft
-          "standard" characters from 128 to 159 (unused by the
-          ISO-8859-x charsets)
-	- The scheduler was chunking the Content-Type field from
-          CGI programs; this problem was most noticeable with
-          Microsoft Internet Explorer 5.
-	- By popular demand, the printers, jobs, and classes
-          CGIs no longer force a reload of the page every 10/30
-          seconds.
-	- The scheduler incorrectly required that the IPP client
-          provide a document-format attribute for the
-          validate-job operation.
-	- Clients that sent bad IPP requests without the
-          required attributes-natural-language and
-          attributes-charset attributes would crash the
-          scheduler.
-
-
-CHANGES IN CUPS v1.0.4
-
-	- Documentation updates.
-	- Jobs would get stuck in the queue and wouldn't print
-	  until you enabled the queue.
-	- The lp and lpr commands now catch SIGHUP and SIGINTR.
-	- The lp and lpr commands now use sigaction or sigset
-	  when available.
-	- CUPS library updates for WIN32/OS-2
-
-
-CHANGES IN CUPS v1.0.3
-
-	- Documentation updates.
-	- The lpq man page was missing.
-	- The configure script was not properly detecting the
-	  image libraries.
-	- The top-level makefile was calling "make" instead of
-	  "$(MAKE)".
-	- PostScript filter fixes for number-up, OutputOrder,
-	  and %Trailer.
-	- The imagetops filter didn't end the base-85 encoding
-	  properly if the image data was not a multiple of 4
-	  bytes in length.
-	- The imagetoraster filter didn't generate good banded
-	  RGB or CMY data (was dividing the line width by 4
-	  instead of 3...)
-	- The imagetoraster filter now records the bounding
-	  box of the image on the page.
-	- The CUPS image library cache code wasn't working as
-	  designed; images larger than the maximum RIP cache
-	  would eventually thrash using the same cache tile.
-	- The CUPS image library TIFF loading code didn't
-	  handle unknown resolution units properly; the fixed
-	  code uses a default resolution of 128 PPI.
-	- cupsGetClasses() and cupsGetPrinters() did not free
-	  existing strings if they ran out of memory.
-	- The scheduler logs incorrectly contained 3 digits for
-	  the timezone offset instead of 4.
-	- The scheduler now does a lookup for the default user
-	  and group ID; the previous hardcoded values caused
-	  problems with the LPD backend.
-	- The cancel-job operation now allows any user in the
-	  system group to cancel any job.
-	- The cancel-job operation stopped the print queue if
-	  the job was being printed.
-	- Now only stop printers if the backend fails. If the
-	  filter fails then the failure is noted in the
-	  error_log and printing continues with the next file in
-	  the queue.
-	- Now log whether a filter fails because of a signal
-	  or because it returned a non-zero exit status.
-	- The root user now always passes the system group test.
-	- Printers with an interface script and remote printers
-	  and classes didn't have a printer-make-and-model
-	  attribute.
-	- Added logging of lost/timed-out remote printers.
-	- The HP-GL/2 filter was scaling the pen width twice.
-	- Updated the HP-GL/2 filter to use a single SP (Set
-	  Pen) procedure.  This makes the output smaller and is
-	  more appropriate since the filter keeps track of the
-	  pen states already.
-	- The scheduler didn't handle passwords with spaces.
-	- The IPP backend now does multiple copies and retries
-	  if the destination server requires it (e.g. HP
-	  JetDirect.)
-	- The disable command didn't implement the "-c" option
-	  (cancel all jobs.)
-	- Changed the CMYK generation function for the image file
-	  and PostScript RIPs.
-	- The lp command didn't support the "-h" option as
-	  documented.
-	- The AppSocket, IPP, and LPD backends now retry on all
-	  network errors.  This should prevent stopped queues
-	  caused by a printer being disconnected from the
-	  network or powered off.
-	- The scheduler now restarts a job if the corresponding
-	  printer is modified.
-	- The image RIPs now rotate the image if needed to fit
-	  on the page.
-
-
-CHANGES IN CUPS v1.0.2
-
-	- The HP-GL/2 filter didn't always scale the output
-	  correctly.
-	- The HP-GL/2 filter now supports changing the page size
-	  automatically when the "fitplot" option is not used.
-	- The cancel-job operation was expecting a resource name
-	  of the form "/job/#" instead of "/jobs/#"; this
-	  prevented the cancel and lprm commands from working.
-	- The backends didn't log pages when files were printed
-	  using the "-oraw" option.
-	- The authorization code did not work with the Slackware
-	  long shadow password package because its crypt() can
-	  return NULL.
-	- The chunking code didn't work for reading the response
-	  of a POST request.
-	- cupsGetPPD() now does authentication as needed.
-	- The N-up code in the PostScript filter didn't work
-	  with some printers (grestoreall would restore the
-	  default blank page and device settings).
-	- The N-up code in the PostScript filter didn't scale
-	  the pages to fit within the imageable area of the
-	  page.
-	- Wasn't doing an fchown() on the request files.  This
-	  caused problems when the default root account group
-	  and CUPS group were not the same.
-
-
-CHANGES IN CUPS v1.0.1
-
-	- Documentation updates.
-	- Fixed a bunch of possible buffer-overflow conditions.
-	- The scheduler now supports authentication using PAM.
-	- Updated the Italian message file.
-	- httpEncode64() didn't add an extra "=" if there was
-	  only one byte in the last three-byte group.
-	- Now drop any trailing character set from the locale
-	  string (e.g. "en_US.ISO_8859-1" becomes "en_US")
-	- Fixed "timezone" vs "tm_gmtoff" usage for BSD-based
-	  operating systems.
-	- Updated IPP security so that "get" operations can be
-	  done from any resource name; this allows the CGIs to
-	  work with printer authentication enabled so long as
-	  authentication isn't turned on for the whole "site".
-	- The IPP code didn't properly handle the "unsupported"
-	  group; this caused problems with the HP JetDirect since
-	  it doesn't seem to support the "copies" attribute.
-	- The HTTP chunking code was missing a CR LF pair at the
-	  end of a 0-length chunk.
-	- The httpSeparate() function didn't handle embedded
-	  usernames and passwords in the URI properly.
-	- Doing "lpadmin -p printer -E" didn't restart printing
-	  if there were pending jobs.
-	- The cancel-job operation now requires either a
-	  requesting-user-name attribute or an authenticated
-	  username.
-	- The add-printer code did not report errors if the
-	  interface script or PPD file could not be renamed.
-	- Request files are now created without world read
-	  permissions.
-	- Added a cupsLastError() function to the CUPS API to
-	  retrieve the IPP error code from the last request.
-	- Options are now case-insensitive.
-	- The lpq command now provides 10 characters for the
-	  username instead of the original (Berkeley standard)
-	  7.
-	- The cancel command needed a local CUPS server to work
-	  (or the appropriate ServerName in cupsd.conf)
-	- The cancel and lprm commands didn't report the IPP
-	  error if the job could not be cancelled.
-	- The lp and lpr commands didn't intercept SIGTERM to
-	  remove temporary files when printing from stdin.
-	- The lp and lpr commands didn't report the IPP error if
-	  the job could not be printed.

-	- The scheduler did not honor MIME type priorities.
-	- The commandtops filter incorrectly used the JCLBegin code to end
-	  its jobs.

 used to submit changes.
-
-
-## HOW TO CONTACT THE DEVELOPERS
-
-The CUPS mailing lists are the primary means of asking questions and informally
-discussing issues and feature requests with the CUPS developers and other
-experienced CUPS users and developers.  The "cups" mailing list is intended for
-CUPS usage questions and new software announcements while the "cups-devel"
-mailing list provides a forum for CUPS developers and monitoring new bugs.
-
-
-## INTERFACES
-
-CUPS interfaces, including the C APIs and command-line arguments, environment
-variables, configuration files, and output format, are stable across patch
-versions and are generally backwards-compatible with interfaces used in prior
-major and minor versions.  However, program interfaces such as those used by
-the scheduler to run filter, port monitor, and backend processes for job
-processing should only be considered stable from the point of view of a
-filter, port monitor, or backend.  Software that simulates the scheduler in
-order to run those programs outside of CUPS must necessarily be updated when
-the corresponding interface is changed in a subsequent CUPS release, otherwise
-undefined behavior can occur.
-
-CUPS C APIs starting with an underscore (_) are considered to be private to
-CUPS and are not subject to the normal guarantees of stability between CUPS
-releases and must never be used in non-CUPS source code.  Similarly,
-configuration and state files written by CUPS are considered private if a
-corresponding man page is not provided with the CUPS release.  Never rely on
-undocumented files or formats when developing software for CUPS.  Always use a
-published C API to access data stored in a file to avoid compatibility problems
-in the future.
-
-
-## BUILD SYSTEM
-
-The CUPS build system uses GNU autoconf to tailor the library to the local
-operating system.  Project files for the current release of Microsoft Visual
-Studio are also provided for Microsoft Windows®.  To improve portability,
-makefiles must not make use of features unique to GNU make.  See the MAKEFILE
-GUIDELINES section for a description of the allowed make features and makefile
-guidelines.
-
-Additional GNU build programs such as GNU automake and GNU libtool must not be
-used.  GNU automake produces non-portable makefiles which depend on GNU-
-specific extensions, and GNU libtool is not portable or reliable enough for
-CUPS.
-
-
-## VERSION NUMBERING
-
-CUPS uses a three-part version number separated by periods to represent the
-major, minor, and patch release numbers.  Major release numbers indicate large
-design changes or backwards-incompatible changes to the CUPS API or CUPS
-Imaging API.  Minor release numbers indicate new features and other smaller
-changes which are backwards-compatible with previous CUPS releases.  Patch
-numbers indicate bug fixes to the previous feature or patch release.
-
-> Note:
->
-> When we talk about compatibility, we are talking about binary compatibility
-> for public APIs and output format compatibility for program interfaces.
-> Changes to configuration file formats or the default behavior of programs
-> are not generally considered incompatible as the upgrade process can
-> normally address such changes gracefully.
-
-Production releases use the plain version numbers:
-
-    MAJOR.MINOR.PATCH
-    1.0.0
-    ...
-    1.1.0
-    ...
-    1.1.23
-    ...
-    2.0.0
-    ...
-    2.1.0
-    2.1.1
-    2.1.2
-    2.1.3
-
-The first production release in a MAJOR.MINOR series (MAJOR.MINOR.0) is called
-a feature release.  Feature releases are the only releases that may contain new
-features.  Subsequent production releases in a MAJOR.MINOR series may only
-contain bug fixes.
-
-Beta-test releases are identified by appending the letter B to the major and
-minor version numbers followed by the beta release number:
-
-    MAJOR.MINORbNUMBER
-    2.2b1
-
-Release candidates are identified by appending the letters RC to the major and
-minor version numbers followed by the release candidate number:
-
-    MAJOR.MINORrcNUMBER
-    2.2rc1
-
-
-## CODING GUIDELINES
-
-Contributed source code must follow the guidelines below.  While the examples
-are for C and C++ source files, source code for other languages should conform
-to the same guidelines as allowed by the language.
-
-
-### SOURCE FILES
-
-All source files names must be 16 characters or less in length to ensure
-compatibility with older UNIX filesystems.  Source files containing functions
-have an extension of ".c" for C and ".cxx" for C++ source files.  All other
-"include" files have an extension of ".h".  Tabs are set to 8 characters or
-columns.
-
-> Note:
->
-> The ".cxx" extension is used because it is the only common C++ extension
-> between Linux, macOS, UNIX, and Windows.
-
-The top of each source file contains a header giving the purpose or nature of
-the source file and the copyright and licensing notice:
-
-    /*
-     * Description of file contents.
-     *
-     * Copyright 2016 by Apple Inc.
-     *
-     * These coded instructions, statements, and computer programs are the
-     * property of Apple Inc. and are protected by Federal copyright
-     * law.  Distribution and use rights are outlined in the file "LICENSE.txt"
-     * which should have been included with this file.  If this file is
-     * file is missing or damaged, see the license at "http://www.cups.org/".
-     */
-
-For source files that are subject to the Apple OS-Developed Software exception,
-the following additional comment appears after the contact information:
-
-     * This file is subject to the Apple OS-Developed Software exception.
-
-
-### HEADER FILES
-
-All public header files must include the "versioning.h" header file, or a header
-that does so.  Function declarations are then "decorated" with the correct
-_CUPS_API_major_minor macro to define its availability based on the build
-environment, for example:
-
-    extern int cupsDoThis(int foo, int bar) _CUPS_API_2_2;
-
-Private API header files must be named with the suffix "-private", for example
-the "cups.h" header file defines all of the public CUPS APIs while the
-"cups-private.h" header file defines all of the private CUPS APIs as well.
-Typically a private API header file will include the corresponding public API
-header file.
-
-
-### COMMENTS
-
-All source code utilizes block comments within functions to describe the
-operations being performed by a group of statements; avoid putting a comment
-per line unless absolutely necessary, and then consider refactoring the code
-so that it is not necessary.  C source files use the block comment format
-("/* comment */") since many vendor C compilers still do not support C99/C++
-comments ("// comment"):
-
-    /*
-     * Clear the state array before we begin...
-     */
-
-     for (i = 0; i < (sizeof(array) / sizeof(sizeof(array[0])); i ++)
-       array[i] = CUPS_STATE_IDLE;
-
-    /*
-     * Wait for state changes on another thread...
-     */
-
-     do
-     {
-       for (i = 0; i < (sizeof(array) / sizeof(sizeof(array[0])); i ++)
-         if (array[i] != CUPS_STATE_IDLE)
-           break;
-
-       if (i == (sizeof(array) / sizeof(array[0])))
-         sleep(1);
-     } while (i == (sizeof(array) / sizeof(array[0])));
-
-
-### INDENTATION
-
-All code blocks enclosed by brackets begin with the opening brace on a new
-line.  The code then follows starting on a new line after the brace and is
-indented 2 spaces.  The closing brace is then placed on a new line following
-the code at the original indentation:
-
-    {
-      int i; /* Looping var */
-
-     /*
-      * Process foobar values from 0 to 999...
-      */
-
-      for (i = 0; i < 1000; i ++)
-      {
-        do_this(i);
-        do_that(i);
-      }
-    }
-
-Single-line statements following "do", "else", "for", "if", and "while" are
-indented 2 spaces as well.  Blocks of code in a "switch" block are indented 4
-spaces after each "case" and "default" case:
-
-    switch (array[i])
-    {
-      case CUPS_STATE_IDLE :
-          do_this(i);
-          do_that(i);
-          break;
-
-      default :
-          do_nothing(i);
-          break;
-    }
-
-
-### SPACING
-
-A space follows each reserved word such as "if", "while", etc.  Spaces are not
-inserted between a function name and the arguments in parenthesis.
-
-
-### RETURN VALUES
-
-Parenthesis surround values returned from a function:
-
-    return (CUPS_STATE_IDLE);
-
-
-### FUNCTIONS
-
-Functions with a global scope have a lowercase prefix followed by capitalized
-words, e.g., "cupsDoThis", "cupsDoThat", "cupsDoSomethingElse", etc.  Private
-global functions begin with a leading underscore, e.g., "\_cupsDoThis",
-"\_cupsDoThat", etc.
-
-Functions with a local scope are declared "static" with lowercase names and
-underscores between words, e.g., "do\_this", "do\_that", "do\_something\_else", etc.
-
-Each function begins with a comment header describing what the function does,
-the possible input limits (if any), the possible output values (if any), and
-any special information needed:
-
-    /*
-     * 'do_this()' - Compute y = this(x).
-     *
-     * Notes: none.
-     */
-
-    static float       /* O - Inverse power value, 0.0 <= y <= 1.1 */
-    do_this(float x)   /* I - Power value (0.0 <= x <= 1.1) */
-    {
-      ...
-      return (y);
-    }
-
-Return/output values are indicated using an "O" prefix, input values are
-indicated using the "I" prefix, and values that are both input and output use
-the "IO" prefix for the corresponding in-line comment.
-
-The Mini-XML documentation generator also understands the following special
-text in the function description comment:
-
-    @deprecated@         - Marks the function as deprecated (not recommended
-                           for new development and scheduled for removal)
-    @since CUPS version@ - Marks the function as new in the specified version
-                           of CUPS.
-    @private@            - Marks the function as private (same as starting the
-                           function name with an underscore)
-
-
-### VARIABLES
-
-Variables with a global scope are capitalized, e.g., "ThisVariable",
-"ThatVariable", "ThisStateVariable", etc.  Globals in CUPS libraries are either
-part of the per-thread global values managed by the "\_cupsGlobals()" function
-or are suitably protected for concurrent access.  Global variables should be
-replaced by function arguments whenever possible.
-
-Variables with a local scope are lowercase with underscores between words,
-e.g., "this\_variable", "that\_variable", etc.  Any "local global" variables
-shared by functions within a source file are declared "static".  As for global
-variables, local static variables are suitably protected for concurrent access.
-
-Each variable is declared on a separate line and is immediately followed by a
-comment block describing the variable:
-
-    int         ThisVariable;    /* The current state of this */
-    static int  that_variable;   /* The current state of that */
-
-
-### TYPES
-
-All type names are lowercase with underscores between words and "\_t" appended
-to the end of the name, e.g., "cups\_this\_type\_t", "cups\_that\_type\_t", etc.
-Type names start with a prefix, typically "cups" or the name of the program,
-to avoid conflicts with system types.  Private type names start with an
-underscore, e.g., "\_cups\_this\_t", "\_cups\_that\_t", etc.
-
-Each type has a comment block immediately after the typedef:
-
-    typedef int cups_this_type_t;  /* This type is for CUPS foobar options. */
-
-
-### STRUCTURES
-
-All structure names are lowercase with underscores between words and "\_s"
-appended to the end of the name, e.g., "cups\_this\_s", "cups\_that\_s", etc.
-Structure names start with a prefix, typically "cups" or the name of the
-program, to avoid conflicts with system types.  Private structure names start
-with an underscore, e.g., "\_cups\_this\_s", "\_cups\_that\_s", etc.
-
-Each structure has a comment block immediately after the struct and each member
-is documented similar to the variable naming policy above:
-
-    struct cups_this_struct_s  /* This structure is for CUPS foobar options. */
-    {
-      int this_member;         /* Current state for this */
-      int that_member;         /* Current state for that */
-    };
-
-
-### CONSTANTS
-
-All constant names are uppercase with underscores between words, e.g.,
-"CUPS\_THIS\_CONSTANT", "CUPS\_THAT\_CONSTANT", etc.  Constants begin with an
-uppercase prefix, typically "CUPS" or the program name.  Private constants
-start with an underscore, e.g., "\_CUPS\_THIS\_CONSTANT", "\_CUPS\_THAT\_CONSTANT",
-etc.
-
-Typed enumerations should be used whenever possible to allow for type checking
-by the compiler.
-
-Comment blocks immediately follow each constant:
-
-    typedef enum cups_tray_e  /* Tray enumerations */
-    {
-      CUPS_TRAY_THIS,         /* This tray */
-      CUPS_TRAY_THAT          /* That tray */
-    } cups_tray_t;
-
-
-## MAKEFILE GUIDELINES
-
-The following is a guide to the makefile-based build system used by CUPS.
-These standards have been developed over the years to allow CUPS to be built on
-as many systems and environments as possible.
-
-
-### GENERAL ORGANIZATION
-
-The CUPS source code is organized functionally into a top-level makefile,
-include file, and subdirectories each with their own makefile and dependencies
-files.  The ".in" files are template files for the autoconf software and are
-used to generate a static version of the corresponding file.
-
-
-### MAKEFILE DOCUMENTATION
-
-Each makefile starts with the standard CUPS header containing the description
-of the file, and CUPS copyright and license notice:
-
-    #
-    # Makefile for ...
-    #
-    # Copyright 2016 by Apple Inc.
-    #
-    # These coded instructions, statements, and computer programs are the
-    # property of Apple Inc. and are protected by Federal copyright
-    # law.  Distribution and use rights are outlined in the file "LICENSE.txt"
-    # which should have been included with this file.  If this file is
-    # file is missing or damaged, see the license at "http://www.cups.org/".
-    #
-
-
-### PORTABLE MAKEFILE CONSTRUCTION
-
-CUPS uses a common subset of make program syntax to ensure that the software
-can be compiled "out of the box" on as many systems as possible.  The following
-is a list of assumptions we follow when constructing makefiles:
-
-- Targets; we assume that the make program supports the notion of simple
-  targets of the form "name:" that perform tab-indented commands that follow
-  the target, e.g.:
-
-      target:
-      TAB target commands
-
-- Dependencies; we assume that the make program supports recursive dependencies
-  on targets, e.g.:
-
-      target: foo bar
-      TAB target commands
-
-      foo: bla
-      TAB foo commands
-
-      bar:
-      TAB bar commands
-
-      bla:
-      TAB bla commands
-
-- Variable Definition; we assume that the make program supports variable
-  definition on the command-line or in the makefile using the following form:
-
-      name=value
-
-- Variable Substitution; we assume that the make program supports variable
-  substitution using the following forms:
-
-      - $(name); substitutes the value of "name",
-      - $(name:.old=.new); substitutes the value of "name" with the filename
-        extension ".old" changed to ".new",
-      - $(MAKEFLAGS); substitutes the command-line options passed to the
-        program without the leading hyphen (-),
-      - $$; substitutes a single $ character,
-      - $<; substitutes the current source file or dependency, and
-      - $@; substitutes the current target name.
-
-- Suffixes; we assume that the make program supports filename suffixes with
-  assumed dependencies, e.g.:
-
-      .SUFFIXES: .c .o
-      .c.o:
-      TAB $(CC) $(CFLAGS) -o $@ -c $<
-
-- Include Files; we assume that the make program supports the include
-  directive, e.g.:
-
-      include ../Makedefs
-      include Dependencies
-
-- Comments; we assume that comments begin with a # character and proceed to the
-  end of the current line.
-
-- Line Length; we assume that there is no practical limit to the length of
-  lines.
-
-- Continuation of long lines; we assume that the \ character may be placed at

-- clean; removes all target programs libraries, documentation files, and object
-  files,
-- depend; generates automatic dependencies for any C or C++ source files (also

-  (also see "INSTALL/UNINSTALL SUPPORT"),
-- install-libs; installs all library files in their corresponding locations
-  (also see "INSTALL/UNINSTALL SUPPORT"), and
-- uninstall; removes all distribution files from their corresponding locations
-  (also see "INSTALL/UNINSTALL SUPPORT").
-
-
-### OBJECT FILES
-
-Object files (the result of compiling a C or C++ source file) have the
-extension ".o".
-
-
-### PROGRAMS
-
-Program files are the result of linking object files and libraries together to
-form an executable file.  A typical program target looks like:
-
-    program: $(OBJS)
-    TAB echo Linking $@...
-    TAB $(CC) $(LDFLAGS) -o $@ $(OBJS) $(LIBS)
-
-### STATIC LIBRARIES
-
-Static libraries have a prefix of "lib" and the extension ".a". A typical
-static library target looks like:
-
-    libname.a: $(OBJECTS)
-    TAB echo Creating $@...
-    TAB $(RM) $@
-    TAB $(AR) $(ARFLAGS) $@ $(OBJECTS)
-    TAB $(RANLIB) $@
-
-### SHARED LIBRARIES
-
-Shared libraries have a prefix of "lib" and the extension ".dylib" or ".so"
-depending on the operating system.  A typical shared library is composed of
-several targets that look like:
-
-    libname.so: $(OBJECTS)
-    TAB echo $(DSOCOMMAND) libname.so.$(DSOVERSION) ...
-    TAB $(DSOCOMMAND) libname.so.$(DSOVERSION) $(OBJECTS)
-    TAB $(RM) libname.so libname.so.$(DSOMAJOR)
-    TAB $(LN) libname.so.$(DSOVERSION) libname.so.$(DSOMAJOR)
-    TAB $(LN) libname.so.$(DSOVERSION) libname.so
-
-    libname.dylib: $(OBJECTS)
-    TAB echo $(DSOCOMMAND) libname.$(DSOVERSION).dylib ...
-    TAB $(DSOCOMMAND) libname.$(DSOVERSION).dylib \
-    TAB TAB -install_name $(libdir)/libname.$(DSOMAJOR).dylib \
-    TAB TAB -current_version libname.$(DSOVERSION).dylib \
-    TAB TAB -compatibility_version $(DSOMAJOR).0 \
-    TAB TAB $(OBJECTS) $(LIBS)
-    TAB $(RM) libname.dylib
-    TAB $(RM) libname.$(DSOMAJOR).dylib
-    TAB $(LN) libname.$(DSOVERSION).dylib libname.$(DSOMAJOR).dylib
-    TAB $(LN) libname.$(DSOVERSION).dylib libname.dylib
-
-### DEPENDENCIES
-
-Static dependencies are expressed in each makefile following the target, for
-example:
-
-    foo: bar
-
-Static dependencies are only used when it is not possible to automatically
-generate them.  Automatic dependencies are stored in a file named
-"Dependencies" and included at the end of the makefile.  The following "depend"
-target rule is used to create the automatic dependencies:
-
-    depend:
-    TAB $(CC) -MM $(ALL_CFLAGS) $(OBJS:.o=.c) >Dependencies
-
-We regenerate the automatic dependencies on an macOS system and express any
-non-macOS dependencies statically in the makefile.
-
-
-### INSTALL/UNINSTALL SUPPORT
-
-All makefiles contains install and uninstall rules which install or remove the
-corresponding software.  These rules must use the $(BUILDROOT) variable as a
-prefix to any installation directory so that CUPS can be installed in a
-temporary location for packaging by programs like rpmbuild.
-
-The $(INSTALL\_BIN), $(INSTALL\_COMPDATA), $(INSTALL\_CONFIG), $(INSTALL\_DATA),
-$(INSTALL\_DIR), $(INSTALL\_LIB), $(INSTALL\_MAN), and $(INSTALL\_SCRIPT) variables
-must be used when installing files so that the proper ownership and permissions
-are set on the installed files.
-
-The $(RANLIB) command must be run on any static libraries after installation
-since the symbol table is invalidated when the library is copied on some
-platforms.

+Developing for CUPS
+===================
+
+Please see the [Contributing to CUPS](CONTRIBUTING.md) file for information on
+contributing to the CUPS project.
+
+
+How To Contact The Developers
+-----------------------------
+
+The CUPS mailing lists are the primary means of asking questions and informally
+discussing issues and feature requests with the CUPS developers and other
+experienced CUPS users and developers.  The "cups" mailing list is intended for
+CUPS usage questions and new software announcements while the "cups-devel"
+mailing list provides a forum for CUPS developers and monitoring new bugs.
+
+
+Interfaces
+----------
+
+CUPS interfaces, including the C APIs and command-line arguments, environment
+variables, configuration files, and output format, are stable across patch
+versions and are generally backwards-compatible with interfaces used in prior
+major and minor versions.  However, program interfaces such as those used by
+the scheduler to run filter, port monitor, and backend processes for job
+processing should only be considered stable from the point of view of a
+filter, port monitor, or backend.  Software that simulates the scheduler in
+order to run those programs outside of CUPS must necessarily be updated when
+the corresponding interface is changed in a subsequent CUPS release, otherwise
+undefined behavior can occur.
+
+CUPS C APIs starting with an underscore (`_`) are considered to be private to
+CUPS and are not subject to the normal guarantees of stability between CUPS
+releases and must never be used in non-CUPS source code.  Similarly,
+configuration and state files written by CUPS are considered private if a
+corresponding man page is not provided with the CUPS release.  Never rely on
+undocumented files or formats when developing software for CUPS.  Always use a
+published C API to access data stored in a file to avoid compatibility problems
+in the future.
+
+
+Build System
+------------
+
+The CUPS build system uses GNU autoconf to tailor the library to the local
+operating system.  Project files for the current release of Microsoft Visual
+Studio are also provided for Microsoft Windows®.  To improve portability,
+makefiles must not make use of features unique to GNU make.  See the MAKEFILE
+GUIDELINES section for a description of the allowed make features and makefile
+guidelines.
+
+Additional GNU build programs such as GNU automake and GNU libtool must not be
+used.  GNU automake produces non-portable makefiles which depend on GNU-
+specific extensions, and GNU libtool is not portable or reliable enough for
+CUPS.
+
+
+Version Numbering
+-----------------
+
+CUPS uses a three-part version number separated by periods to represent the
+major, minor, and patch release numbers.  Major release numbers indicate large
+design changes or backwards-incompatible changes to the CUPS API or CUPS
+Imaging API.  Minor release numbers indicate new features and other smaller
+changes which are backwards-compatible with previous CUPS releases.  Patch
+numbers indicate bug fixes to the previous feature or patch release.  This
+version numbering scheme is consistent with the
+[Semantic Versioning](http://semver.org) specification.
+
+> Note:
+>
+> When we talk about compatibility, we are talking about binary compatibility
+> for public APIs and output format compatibility for program interfaces.
+> Changes to configuration file formats or the default behavior of programs
+> are not generally considered incompatible as the upgrade process can
+> normally address such changes gracefully.
+
+Production releases use the plain version numbers:
+
+    MAJOR.MINOR.PATCH
+    1.0.0
+    ...
+    1.1.0
+    ...
+    1.1.23
+    ...
+    2.0.0
+    ...
+    2.1.0
+    2.1.1
+    2.1.2
+    2.1.3
+
+The first production release in a MAJOR.MINOR series (MAJOR.MINOR.0) is called
+a feature release.  Feature releases are the only releases that may contain new
+features.  Subsequent production releases in a MAJOR.MINOR series may only
+contain bug fixes.
+
+Beta-test releases are identified by appending the letter B to the major and
+minor version numbers followed by the beta release number:
+
+    MAJOR.MINORbNUMBER
+    2.2b1
+
+Release candidates are identified by appending the letters RC to the major and
+minor version numbers followed by the release candidate number:
+
+    MAJOR.MINORrcNUMBER
+    2.2rc1
+
+
+Coding Guidelines
+-----------------
+
+Contributed source code must follow the guidelines below.  While the examples
+are for C and C++ source files, source code for other languages should conform
+to the same guidelines as allowed by the language.
+
+Source code comments provide the reference portion of the CUPS Programming
+Manual, which is generated using the [codedoc](https://www.msweet.org/codedoc)
+software.
+
+
+### Source Files
+
+All source files names must be 16 characters or less in length to ensure
+compatibility with older UNIX filesystems.  Source files containing functions
+have an extension of ".c" for C and ".cxx" for C++ source files.  All other
+"include" files have an extension of ".h".  Tabs are set to 8 characters or
+columns.
+
+> Note:
+>
+> The ".cxx" extension is used because it is the only common C++ extension
+> between Linux, macOS, UNIX, and Windows.
+
+The top of each source file contains a header giving the purpose or nature of
+the source file and the copyright and licensing notice:
+
+    /*
+     * Description of file contents.
+     *
+     * Copyright 2017 by Apple Inc.
+     *
+     * Licensed under Apache License v2.0.  See the file "LICENSE" for more
+     * information.
+     */
+
+
+### Header Files
+
+All public header files must include the "versioning.h" header file, or a header
+that does so.  Function declarations are then "decorated" with the correct
+`_CUPS_API_major_minor` macro to define its availability based on the build
+environment, for example:
+
+    extern int cupsDoThis(int foo, int bar) _CUPS_API_2_2;
+
+Private API header files must be named with the suffix "-private", for example
+the "cups.h" header file defines all of the public CUPS APIs while the
+"cups-private.h" header file defines all of the private CUPS APIs as well.
+Typically a private API header file will include the corresponding public API
+header file.
+
+
+### Comments
+
+All source code utilizes block comments within functions to describe the
+operations being performed by a group of statements; avoid putting a comment
+per line unless absolutely necessary, and then consider refactoring the code
+so that it is not necessary.  C source files use the block comment format
+("/* comment */") since many vendor C compilers still do not support C99/C++
+comments ("// comment"):
+
+    /*
+     * Clear the state array before we begin...
+     */
+
+     for (i = 0; i < (sizeof(array) / sizeof(sizeof(array[0])); i ++)
+       array[i] = CUPS_STATE_IDLE;
+
+    /*
+     * Wait for state changes on another thread...
+     */
+
+     do
+     {
+       for (i = 0; i < (sizeof(array) / sizeof(sizeof(array[0])); i ++)
+         if (array[i] != CUPS_STATE_IDLE)
+           break;
+
+       if (i == (sizeof(array) / sizeof(array[0])))
+         sleep(1);
+     } while (i == (sizeof(array) / sizeof(array[0])));
+
+
+### Indentation
+
+All code blocks enclosed by brackets begin with the opening brace on a new
+line.  The code then follows starting on a new line after the brace and is
+indented 2 spaces.  The closing brace is then placed on a new line following
+the code at the original indentation:
+
+    {
+      int i; /* Looping var */
+
+     /*
+      * Process foobar values from 0 to 999...
+      */
+
+      for (i = 0; i < 1000; i ++)
+      {
+        do_this(i);
+        do_that(i);
+      }
+    }
+
+Single-line statements following "do", "else", "for", "if", and "while" are
+indented 2 spaces as well.  Blocks of code in a "switch" block are indented 4
+spaces after each "case" and "default" case:
+
+    switch (array[i])
+    {
+      case CUPS_STATE_IDLE :
+          do_this(i);
+          do_that(i);
+          break;
+
+      default :
+          do_nothing(i);
+          break;
+    }
+
+
+### Spacing
+
+A space follows each reserved word such as `if`, `while`, etc.  Spaces are not
+inserted between a function name and the arguments in parenthesis.
+
+
+### Return Values
+
+Parenthesis surround values returned from a function:
+
+    return (CUPS_STATE_IDLE);
+
+
+### Functions
+
+Functions with a global scope have a lowercase prefix followed by capitalized
+words, e.g., `cupsDoThis`, `cupsDoThat`, `cupsDoSomethingElse`, etc.  Private
+global functions begin with a leading underscore, e.g., `_cupsDoThis`,
+`_cupsDoThat`, etc.
+
+Functions with a local scope are declared static with lowercase names and
+underscores between words, e.g., `do_this`, `do_that`, `do_something_else`, etc.
+
+Each function begins with a comment header describing what the function does,
+the possible input limits (if any), the possible output values (if any), and
+any special information needed:
+
+    /*
+     * 'do_this()' - Compute y = this(x).
+     *
+     * Notes: none.
+     */
+
+    static float       /* O - Inverse power value, 0.0 <= y <= 1.1 */
+    do_this(float x)   /* I - Power value (0.0 <= x <= 1.1) */
+    {
+      ...
+      return (y);
+    }
+
+Return/output values are indicated using an "O" prefix, input values are
+indicated using the "I" prefix, and values that are both input and output use
+the "IO" prefix for the corresponding in-line comment.
+
+The [codedoc](https://www.msweet.org/codedoc) documentation generator also
+understands the following special text in the function description comment:
+
+    @deprecated@         - Marks the function as deprecated: not recommended
+                           for new development and scheduled for removal.
+    @link name@          - Provides a hyperlink to the corresponding function
+                           or type definition.
+    @since CUPS version@ - Marks the function as new in the specified version
+                           of CUPS.
+    @private@            - Marks the function as private so it will not be
+                           included in the documentation.
+
+
+### Variables
+
+Variables with a global scope are capitalized, e.g., `ThisVariable`,
+`ThatVariable`, `ThisStateVariable`, etc.  Globals in CUPS libraries are either
+part of the per-thread global values managed by the `_cupsGlobals` function
+or are suitably protected for concurrent access.  Global variables should be
+replaced by function arguments whenever possible.
+
+Variables with a local scope are lowercase with underscores between words,
+e.g., `this_variable`, `that_variable`, etc.  Any "local global" variables
+shared by functions within a source file are declared static.  As for global
+variables, local static variables are suitably protected for concurrent access.
+
+Each variable is declared on a separate line and is immediately followed by a
+comment block describing the variable:
+
+    int         ThisVariable;    /* The current state of this */
+    static int  that_variable;   /* The current state of that */
+
+
+### Types
+
+All type names are lowercase with underscores between words and `_t` appended
+to the end of the name, e.g., `cups_this_type_t`, `cups_that_type_t`, etc.
+Type names start with a prefix, typically `cups` or the name of the program,
+to avoid conflicts with system types.  Private type names start with an
+underscore, e.g., `_cups_this_t`, `_cups_that_t`, etc.
+
+Each type has a comment block immediately after the typedef:
+
+    typedef int cups_this_type_t;  /* This type is for CUPS foobar options. */
+
+
+### Structures
+
+All structure names are lowercase with underscores between words and `_s`
+appended to the end of the name, e.g., `cups_this_s`, `cups_that_s`, etc.
+Structure names start with a prefix, typically `cups` or the name of the
+program, to avoid conflicts with system types.  Private structure names start
+with an underscore, e.g., `_cups_this_s`, `_cups_that_s`, etc.
+
+Each structure has a comment block immediately after the struct and each member
+is documented similar to the variable naming policy above:
+
+    struct cups_this_struct_s  /* This structure is for CUPS foobar options. */
+    {
+      int this_member;         /* Current state for this */
+      int that_member;         /* Current state for that */
+    };
+
+
+### Constants
+
+All constant names are uppercase with underscores between words, e.g.,
+`CUPS_THIS_CONSTANT`, `CUPS_THAT_CONSTANT`, etc.  Constants begin with an
+uppercase prefix, typically `CUPS_` or the program or type name.  Private
+constants start with an underscore, e.g., `_CUPS_THIS_CONSTANT`,
+`_CUPS_THAT_CONSTANT`, etc.
+
+Typed enumerations should be used whenever possible to allow for type checking
+by the compiler.
+
+Comment blocks immediately follow each constant:
+
+    typedef enum cups_tray_e  /* Tray enumerations */
+    {
+      CUPS_TRAY_THIS,         /* This tray */
+      CUPS_TRAY_THAT          /* That tray */
+    } cups_tray_t;
+
+
+## Makefile Guidelines
+
+The following is a guide to the makefile-based build system used by CUPS.
+These standards have been developed over the years to allow CUPS to be built on
+as many systems and environments as possible.
+
+
+### General Organization
+
+The CUPS source code is organized functionally into a top-level makefile,
+include file, and subdirectories each with their own makefile and dependencies
+files.  The ".in" files are template files for the autoconf software and are
+used to generate a static version of the corresponding file.
+
+
+### Makefile Documentation
+
+Each makefile starts with the standard CUPS header containing the description
+of the file, and CUPS copyright and license notice:
+
+    #
+    # Makefile for ...
+    #
+    # Copyright 2017 by Apple Inc.
+    #
+    # Licensed under Apache License v2.0.  See the file "LICENSE" for more
+    # information.
+    #
+
+
+### Portable Makefile Construction
+
+CUPS uses a common subset of make program syntax to ensure that the software
+can be compiled "out of the box" on as many systems as possible.  The following
+is a list of assumptions we follow when constructing makefiles:
+
+- Targets; we assume that the make program supports the notion of simple
+  targets of the form "name:" that perform tab-indented commands that follow
+  the target, e.g.:
+
+      target:
+      TAB target commands
+
+- Dependencies; we assume that the make program supports recursive dependencies
+  on targets, e.g.:
+
+      target: foo bar
+      TAB target commands
+
+      foo: bla
+      TAB foo commands
+
+      bar:
+      TAB bar commands
+
+      bla:
+      TAB bla commands
+
+- Variable Definition; we assume that the make program supports variable
+  definition on the command-line or in the makefile using the following form:
+
+      name=value
+
+- Variable Substitution; we assume that the make program supports variable
+  substitution using the following forms:
+
+      - `$(name)`; substitutes the value of "name",
+      - `$(name:.old=.new)`; substitutes the value of "name" with the filename
+        extension ".old" changed to ".new",
+      - `$(MAKEFLAGS)`; substitutes the command-line options passed to the
+        program without the leading hyphen (-),
+      - `$$`; substitutes a single $ character,
+      - `$<`; substitutes the current source file or dependency, and
+      - `$@`; substitutes the current target name.
+
+- Suffixes; we assume that the make program supports filename suffixes with
+  assumed dependencies, e.g.:
+
+      .SUFFIXES: .c .o
+      .c.o:
+      TAB $(CC) $(CFLAGS) -o $@ -c $<
+
+- Include Files; we assume that the make program supports the include
+  directive, e.g.:
+
+      include ../Makedefs
+      include Dependencies
+
+- Comments; we assume that comments begin with a # character and proceed to the
+  end of the current line.
+
+- Line Length; we assume that there is no practical limit to the length of
+  lines.
+
+- Continuation of long lines; we assume that the `\` character may be placed at
+  the end of a line to concatenate two or more lines in a makefile to form a
+  single long line.
+
+- Shell; we assume a POSIX-compatible shell is present on the build system.
+
+
+### Standard Variables
+
+The following variables are defined in the "Makedefs" file generated by the
+autoconf software:
+
+- `ALL_CFLAGS`; the combined C compiler options,
+- `ALL_CXXFLAGS`; the combined C++ compiler options,
+- `AMANDIR`; the administrative man page installation directory (section 8/1m
+  depending on the platform),
+- `AR`; the library archiver command,
+- `ARFLAGS`; options for the library archiver command,
+- `AWK`; the local awk command,
+- `BINDIR`; the binary installation directory,
+- `BUILDROOT`; optional installation prefix (defaults to DSTROOT),

+- `all`; creates all target programs, libraries, and documentation files,
+- `clean`; removes all target programs libraries, documentation files, and object
+  files,
+- `depend`; generates automatic dependencies for any C or C++ source files (also

+  the "clean" target,
+- `install`; installs all distribution files in their corresponding locations
+  (also see "INSTALL/UNINSTALL SUPPORT"),
+- `install-data`; installs all data files in their corresponding locations (also
+  see "INSTALL/UNINSTALL SUPPORT"),
+- `install-exec`; installs all executable files in their corresponding locations
+  (also see "INSTALL/UNINSTALL SUPPORT"),
+- `install-headers`; installs all include files in their corresponding locations
+  (also see "INSTALL/UNINSTALL SUPPORT"),
+- `install-libs`; installs all library files in their corresponding locations
+  (also see "INSTALL/UNINSTALL SUPPORT"), and
+- `uninstall`; removes all distribution files from their corresponding locations
+  (also see "INSTALL/UNINSTALL SUPPORT").
+
+
+### Object Files
+
+Object files (the result of compiling a C or C++ source file) have the
+extension ".o".
+
+
+### Programs
+
+Program files are the result of linking object files and libraries together to
+form an executable file.  A typical program target looks like:
+
+    program: $(OBJS)
+    TAB echo Linking $@...
+    TAB $(CC) $(LDFLAGS) -o $@ $(OBJS) $(LIBS)
+
+### Static Libraries
+
+Static libraries have a prefix of "lib" and the extension ".a". A typical
+static library target looks like:
+
+    libname.a: $(OBJECTS)
+    TAB echo Creating $@...
+    TAB $(RM) $@
+    TAB $(AR) $(ARFLAGS) $@ $(OBJECTS)
+    TAB $(RANLIB) $@
+
+### Shared Libraries
+
+Shared libraries have a prefix of "lib" and the extension ".dylib" or ".so"
+depending on the operating system.  A typical shared library is composed of
+several targets that look like:
+
+    libname.so: $(OBJECTS)
+    TAB echo $(DSOCOMMAND) libname.so.$(DSOVERSION) ...
+    TAB $(DSOCOMMAND) libname.so.$(DSOVERSION) $(OBJECTS)
+    TAB $(RM) libname.so libname.so.$(DSOMAJOR)
+    TAB $(LN) libname.so.$(DSOVERSION) libname.so.$(DSOMAJOR)
+    TAB $(LN) libname.so.$(DSOVERSION) libname.so
+
+    libname.dylib: $(OBJECTS)
+    TAB echo $(DSOCOMMAND) libname.$(DSOVERSION).dylib ...
+    TAB $(DSOCOMMAND) libname.$(DSOVERSION).dylib \
+    TAB TAB -install_name $(libdir)/libname.$(DSOMAJOR).dylib \
+    TAB TAB -current_version libname.$(DSOVERSION).dylib \
+    TAB TAB -compatibility_version $(DSOMAJOR).0 \
+    TAB TAB $(OBJECTS) $(LIBS)
+    TAB $(RM) libname.dylib
+    TAB $(RM) libname.$(DSOMAJOR).dylib
+    TAB $(LN) libname.$(DSOVERSION).dylib libname.$(DSOMAJOR).dylib
+    TAB $(LN) libname.$(DSOVERSION).dylib libname.dylib
+
+### Dependencies
+
+Static dependencies are expressed in each makefile following the target, for
+example:
+
+    foo: bar
+
+Static dependencies are only used when it is not possible to automatically
+generate them.  Automatic dependencies are stored in a file named
+"Dependencies" and included at the end of the makefile.  The following "depend"
+target rule is used to create the automatic dependencies:
+
+    depend:
+    TAB $(CC) -MM $(ALL_CFLAGS) $(OBJS:.o=.c) >Dependencies
+
+We regenerate the automatic dependencies on an macOS system and express any
+non-macOS dependencies statically in the makefile.
+
+
+### Install/Uninstall Support
+
+All makefiles contains install and uninstall rules which install or remove the
+corresponding software.  These rules must use the $(BUILDROOT) variable as a
+prefix to any installation directory so that CUPS can be installed in a
+temporary location for packaging by programs like rpmbuild.
+
+The `INSTALL_BIN`, `INSTALL_COMPDATA`, `INSTALL_CONFIG`, `INSTALL_DATA`,
+`INSTALL_DIR`, `INSTALL_LIB`, `INSTALL_MAN`, and `INSTALL_SCRIPT` variables
+must be used when installing files so that the proper ownership and permissions
+are set on the installed files.
+
+The `$(RANLIB)` command must be run on any static libraries after installation
+since the symbol table is invalidated when the library is copied on some
+platforms.

+INSTALL - CUPS v2.3.3 - 2020-04-24
+==================================
+
+This file describes how to compile and install CUPS from source code. For more
+information on CUPS see the file called "README.md".  A complete change log can
+be found in "CHANGES.md".
+
+Using CUPS requires additional third-party support software and printer drivers.
+These are typically included with your operating system distribution.  Apple
+does not endorse or support third-party support software for CUPS.
+
+> Note: Current versions of macOS DO NOT allow installation to /usr with the
+> default System Integrity Protection (SIP) settings.  In addition, we do not
+> recommend replacing the CUPS supplied with macOS because:
+>
+> a. not all versions of CUPS are compatible with every macOS release,
+>
+> b. code signing prevents replacement of system libraries and access to the
+>    system keychain (needed for encrypted printer sharing), and
+>
+> c. software updates will often replace parts of your local installation,
+>    potentially rendering your system unusable.
+>
+> Apple only supports using the Clang supplied with Xcode to build CUPS on
+> macOS.
+
+
+BEFORE YOU BEGIN
+----------------
+
+You'll need ANSI-compliant C and C++ compilers, plus a make program and POSIX-
+compliant shell (/bin/sh).  The GNU compiler tools and Bash work well and we
+have tested the current CUPS code against several versions of GCC with excellent
+results.
+
+The makefiles used by the project should work with most versions of make.  We've
+tested them with GNU make as well as the make programs shipped by Compaq, HP,
+SGI, and Sun.  BSD users should use GNU make (gmake) since BSD make does not
+support "include".
+
+Besides these tools you'll want ZLIB library for compression support, the GNU
+TLS library for encryption support on platforms other than iOS, macOS, or
+Windows, and either MIT (1.6.3 or higher) or Heimdal Kerberos for Kerberos
+support.  CUPS will compile and run without these, however you'll miss out on
+many of the features provided by CUPS.
+
+On a stock Ubuntu install, the following command will install the required
+prerequisites:
+
+    sudo apt-get install autoconf build-essential libavahi-client-dev \
+         libgnutls28-dev libkrb5-dev libnss-mdns libpam-dev \
+         libsystemd-dev libusb-1.0-0-dev zlib1g-dev
+
+Also, please note that CUPS does not include print filters to support PDF or
+raster printing.  You *must* download GPL Ghostscript and/or the Open Printing
+CUPS filters package separately to print on operating systems other than macOS.
+
+
+CONFIGURATION
+-------------
+
+CUPS uses GNU autoconf, so you should find the usual "configure" script in the
+main CUPS source directory.  To configure CUPS for your system, type:
+
+    ./configure
+
+The default installation will put the CUPS software in the "/etc", "/usr", and
+"/var" directories on your system, which will overwrite any existing printing
+commands on your system.  Use the `--prefix` option to install the CUPS software
+in another location:
+
+    ./configure --prefix=/some/directory
+
+> Note: Current versions of macOS DO NOT allow installation to /usr with the
+> default System Integrity Protection (SIP) settings.
+
+To see a complete list of configuration options, use the `--help` option:
+
+    ./configure --help
+
+If any of the dependent libraries are not installed in a system default location
+(typically "/usr/include" and "/usr/lib") you'll need to set the CFLAGS,
+CPPFLAGS, CXXFLAGS, DSOFLAGS, and LDFLAGS environment variables prior to running
+configure:
+
+    setenv CFLAGS "-I/some/directory"
+    setenv CPPFLAGS "-I/some/directory"
+    setenv CXXFLAGS "-I/some/directory"
+    setenv DSOFLAGS "-L/some/directory"
+    setenv LDFLAGS "-L/some/directory"
+    ./configure ...
+
+or:
+
+    CFLAGS="-I/some/directory" \
+    CPPFLAGS="-I/some/directory" \
+    CXXFLAGS="-I/some/directory" \
+    DSOFLAGS="-L/some/directory" \
+    LDFLAGS="-L/some/directory" \
+    ./configure ...
+
+The `--enable-debug` option compiles CUPS with debugging information enabled.
+Additional debug logging support can be enabled using the
+`--enable-debug-printfs` option - these debug messages are enabled using the
+`CUPS_DEBUG_xxx` environment variables at run-time.
+
+CUPS also includes an extensive set of unit tests that can be used to find and
+diagnose a variety of common problems - use the "--enable-unit-tests" configure
+option to run them at build time.
+
+On macOS, use the `--with-archflags` option to build with the correct set of
+architectures:
+
+    ./configure --with-archflags="-arch i386 -arch x86_64" ...
+
+Once you have configured things, just type:
+
+    make ENTER
+
+or if you have FreeBSD, NetBSD, or OpenBSD type:
+
+    gmake ENTER
+
+to build the software.
+
+
+TESTING THE SOFTWARE
+--------------------
+
+Aside from the built-in unit tests, CUPS includes an automated test framework
+for testing the entire printing system.  To run the tests, just type:
+
+    make check ENTER
+
+or if you have FreeBSD, NetBSD, or OpenBSD type:
+
+    gmake check ENTER
+
+The test framework runs a copy of the CUPS scheduler (cupsd) on port 8631 in
+/tmp/cups-$USER and produces a nice HTML report of the results.
+
+
+INSTALLING THE SOFTWARE
+-----------------------
+
+Once you have built the software you need to install it.  The "install" target
+provides a quick way to install the software on your local system:
+
+    make install ENTER
+
+or for FreeBSD, NetBSD, or OpenBSD:
+
+    gmake install ENTER
+
+Use the BUILDROOT variable to install to an alternate root directory:
+
+    make BUILDROOT=/some/other/root/directory install ENTER
+
+You can also build binary packages that can be installed on other machines using
+the RPM spec file ("packaging/cups.spec") or EPM list file
+("packaging/cups.list").  The latter also supports building of binary RPMs, so
+it may be more convenient to use.
+
+You can find the RPM software at:
+
+    http://www.rpm.org/
+
+The EPM software is available at:
+
+    https://michaelrsweet.github.io/epm
+
+
+CREATING BINARY DISTRIBUTIONS WITH EPM
+--------------------------------------
+
+The top level makefile supports generation of many types of binary distributions
+using EPM.  To build a binary distribution type:
+
+    make <format> ENTER
+
+or
+
+    gmake <format> ENTER
+
+for FreeBSD, NetBSD, and OpenBSD.  The <format> target is one of the following:
+
+- "epm": Builds a script + tarfile package
+- "bsd": Builds a *BSD package
+- "deb": Builds a Debian package
+- "pkg": Builds a Solaris package
+- "rpm": Builds a RPM package
+- "slackware": Build a Slackware package
+
+
+GETTING DEBUG LOGGING FROM CUPS
+-------------------------------
+
+When configured with the `--enable-debug-printfs` option, CUPS compiles in
+additional debug logging support in the scheduler, CUPS API, and CUPS Imaging
+API.  The following environment variables are used to enable and control debug
+logging:
+
+- `CUPS_DEBUG_FILTER`: Specifies a POSIX regular expression to control which
+  messages are logged.
+- `CUPS_DEBUG_LEVEL`: Specifies a number from 0 to 9 to control the verbosity of
+  the logging. The default level is 1.
+- `CUPS_DEBUG_LOG`: Specifies a log file to use.  Specify the name "-" to send
+  the messages to stderr.  Prefix a filename with "+" to append to an existing
+  file.  You can include a single "%d" in the filename to embed the current
+  process ID.
+
+
+REPORTING PROBLEMS
+------------------
+
+If you have problems, *read the documentation first*!  If the documentation does
+not solve your problems, please post a message on the users forum at:
+
+    https://www.cups.org/
+
+Include your operating system and version, compiler and version, and any errors
+or problems you've run into.  The "config.log" file and the output from the
+configure script and make should also be sent, as it often helps to determine
+the cause of your problem.
+
+If you are running a version of Linux, be sure to provide the Linux distribution
+you have, too.

+      the original version of the Work and any modifications or additions
+      to that Work or Derivative Works thereof, that is intentionally
+      submitted to Licensor for inclusion in the Work by the copyright owner
+      or by an individual or Legal Entity authorized to submit on behalf of
+      the copyright owner. For the purposes of this definition, "submitted"
+      means any form of electronic, verbal, or written communication sent
+      to the Licensor or its representatives, including but not limited to
+      communication on electronic mailing lists, source code control systems,
+      and issue tracking systems that are managed by, or on behalf of, the
+      Licensor for the purpose of discussing and improving the Work, but
+      excluding communication that is conspicuously marked or otherwise
+      designated in writing by the copyright owner as "Not a Contribution."
+
+      "Contributor" shall mean Licensor and any individual or Legal Entity
+      on behalf of whom a Contribution has been received by Licensor and
+      subsequently incorporated within the Work.
+
+   2. Grant of Copyright License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,
+      where such license applies only to those patent claims licensable
+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
+
+   END OF TERMS AND CONDITIONS

-INTRODUCTION
-
-CUPS(tm) is provided under the GNU General Public License ("GPL")
-and GNU Library General Public License ("LGPL"), Version 2, with an
-exception for Apple operating systems. A copy of the exception and
-licenses follow this introduction.
-
-The GNU LGPL applies to the CUPS and CUPS Imaging libraries
-located in the "cups" and "filter" subdirectories of the CUPS
-source distribution and the files in the "test" subdirectory. The
-GNU GPL applies to the remainder of the CUPS distribution.
-
-For those not familiar with the GNU GPL, the license basically
-allows you to:
-
-   - Use the CUPS software at no charge.
-   - Distribute verbatim copies of the software in source or
-     binary form.
-   - Sell verbatim copies of the software for a media fee, or
-     sell support for the software.
-
-What this license *does not* allow you to do is make changes or
-add features to CUPS and then sell a binary distribution without
-source code. You must provide source for any changes or additions
-to the software, and all code must be provided under the GPL or
-LGPL as appropriate. The only exceptions to this are the portions
-of the CUPS software covered by the Apple operating system
-license exceptions outlined later in this license agreement.
-
-The GNU LGPL relaxes the "link-to" restriction, allowing you to
-develop applications that use the CUPS and CUPS Imaging libraries
-under other licenses and/or conditions as appropriate for your
-application, driver, or filter.
-
-
-LICENSE EXCEPTIONS
-
-In addition, as the copyright holder of CUPS, Apple Inc. grants
-the following special exception:
-
-     1. Apple Operating System Development License Exception;
-
-	a. Software that is developed by any person or entity
-	   for an Apple Operating System ("Apple OS-Developed
-	   Software"), including but not limited to Apple and
-	   third party printer drivers, filters, and backends
-	   for an Apple Operating System, that is linked to the
-	   CUPS imaging library or based on any sample filters
-	   or backends provided with CUPS shall not be
-	   considered to be a derivative work or collective work
-	   based on the CUPS program and is exempt from the
-	   mandatory source code release clauses of the GNU GPL.
-	   You may therefore distribute linked combinations of
-	   the CUPS imaging library with Apple OS-Developed
-	   Software without releasing the source code of the
-	   Apple OS-Developed Software. You may also use sample
-	   filters and backends provided with CUPS to develop
-	   Apple OS-Developed Software without releasing the
-	   source code of the Apple OS-Developed Software.
-
-	b. An Apple Operating System means any operating system
-	   software developed and/or marketed by Apple Inc.,
-	   including but not limited to all existing releases and
-	   versions of Apple's Darwin, iOS, macOS, macOS Server, and
-	   tvOS products and all follow-on releases and future
-	   versions thereof.
-
-	c. This exception is only available for Apple
-	   OS-Developed Software and does not apply to software
-	   that is distributed for use on other operating
-	   systems.
-
-	d. All CUPS software that falls under this license
-	   exception have the following text at the top of each
-	   source file:
-
-	     This file is subject to the Apple OS-Developed
-	     Software exception.
-
-No developer is required to provide this exception in a derived
-work.

-KERBEROS SUPPORT CODE
-
-The Kerberos support code ("KSC") is copyright 2006 by Jelmer
-Vernooij and is provided 'as-is', without any express or implied
-warranty.  In no event will the author or Apple Inc. be held
-liable for any damages arising from the use of the KSC.
-
-Sources files containing KSC have the following text at the top
-of each source file:
-
-     This file contains Kerberos support code, copyright 2006 by
-     Jelmer Vernooij.
-
-The KSC copyright and license apply only to Kerberos-related
-feature code in CUPS.  Such code is typically conditionally
-compiled based on the present of the HAVE_GSSAPI preprocessor
-definition.
-
-Permission is granted to anyone to use the KSC for any purpose,
-including commercial applications, and to alter it and
-redistribute it freely, subject to the following restrictions:
-
-     1. The origin of the KSC must not be misrepresented; you
-	must not claim that you wrote the original software. If
-	you use the KSC in a product, an acknowledgment in the
-	product documentation would be appreciated but is not
-	required.
-
-     2. Altered source versions must be plainly marked as such,
-	and must not be misrepresented as being the original
-	software.
-
-     3. This notice may not be removed or altered from any source
-	distribution.
-
-
-TRADEMARKS
-
-CUPS and the CUPS logo (the "CUPS Marks") are trademarks of Apple
-Inc. Apple grants you a non-exclusive and non-transferable right
-to use the CUPS Marks in any direct port or binary distribution
-incorporating CUPS software and in any promotional material
-therefor.  You agree that your products will meet the highest
-levels of quality and integrity for similar goods, not be unlawful,
-and be developed, manufactured, and distributed in compliance with
-this license.  You will not interfere with Apple's rights in the
-CUPS Marks, and all use of the CUPS Marks shall inure to the
-benefit of Apple.  This license does not apply to use of the CUPS
-Marks in a derivative products, which requires prior written
-permission from Apple Inc.

-		    GNU GENERAL PUBLIC LICENSE
-		       Version 2, June 1991
-
- Copyright (C) 1989, 1991 Free Software Foundation, Inc.
-                       59 Temple Place, Suite 330, Boston, MA  02111-1307  USA
- Everyone is permitted to copy and distribute verbatim copies
- of this license document, but changing it is not allowed.
-
-			    Preamble
-
-  The licenses for most software are designed to take away your
-freedom to share and change it.  By contrast, the GNU General Public
-License is intended to guarantee your freedom to share and change free
-software--to make sure the software is free for all its users.  This
-General Public License applies to most of the Free Software
-Foundation's software and to any other program whose authors commit to
-using it.  (Some other Free Software Foundation software is covered by
-the GNU Library General Public License instead.)  You can apply it to
-your programs, too.
-
-  When we speak of free software, we are referring to freedom, not
-price.  Our General Public Licenses are designed to make sure that you
-have the freedom to distribute copies of free software (and charge for
-this service if you wish), that you receive source code or can get it
-if you want it, that you can change the software or use pieces of it
-in new free programs; and that you know you can do these things.
-
-  To protect your rights, we need to make restrictions that forbid
-anyone to deny you these rights or to ask you to surrender the rights.
-These restrictions translate to certain responsibilities for you if you
-distribute copies of the software, or if you modify it.
-
-  For example, if you distribute copies of such a program, whether
-gratis or for a fee, you must give the recipients all the rights that
-you have.  You must make sure that they, too, receive or can get the
-source code.  And you must show them these terms so they know their
-rights.
-
-  We protect your rights with two steps: (1) copyright the software, and
-(2) offer you this license which gives you legal permission to copy,
-distribute and/or modify the software.
-
-  Also, for each author's protection and ours, we want to make certain
-that everyone understands that there is no warranty for this free
-software.  If the software is modified by someone else and passed on, we
-want its recipients to know that what they have is not the original, so
-that any problems introduced by others will not reflect on the original
-authors' reputations.
-
-  Finally, any free program is threatened constantly by software
-patents.  We wish to avoid the danger that redistributors of a free
-program will individually obtain patent licenses, in effect making the
-program proprietary.  To prevent this, we have made it clear that any
-patent must be licensed for everyone's free use or not licensed at all.
-
-  The precise terms and conditions for copying, distribution and
-modification follow.
-
-		    GNU GENERAL PUBLIC LICENSE
-   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
-
-  0. This License applies to any program or other work which contains
-a notice placed by the copyright holder saying it may be distributed
-under the terms of this General Public License.  The "Program", below,
-refers to any such program or work, and a "work based on the Program"
-means either the Program or any derivative work under copyright law:
-that is to say, a work containing the Program or a portion of it,
-either verbatim or with modifications and/or translated into another
-language.  (Hereinafter, translation is included without limitation in
-the term "modification".)  Each licensee is addressed as "you".
-
-Activities other than copying, distribution and modification are not
-covered by this License; they are outside its scope.  The act of
-running the Program is not restricted, and the output from the Program
-is covered only if its contents constitute a work based on the
-Program (independent of having been made by running the Program).
-Whether that is true depends on what the Program does.
-
-  1. You may copy and distribute verbatim copies of the Program's
-source code as you receive it, in any medium, provided that you
-conspicuously and appropriately publish on each copy an appropriate
-copyright notice and disclaimer of warranty; keep intact all the
-notices that refer to this License and to the absence of any warranty;
-and give any other recipients of the Program a copy of this License
-along with the Program.
-
-You may charge a fee for the physical act of transferring a copy, and
-you may at your option offer warranty protection in exchange for a fee.
-
-  2. You may modify your copy or copies of the Program or any portion
-of it, thus forming a work based on the Program, and copy and
-distribute such modifications or work under the terms of Section 1
-above, provided that you also meet all of these conditions:
-
-    a) You must cause the modified files to carry prominent notices
-    stating that you changed the files and the date of any change.
-
-    b) You must cause any work that you distribute or publish, that in
-    whole or in part contains or is derived from the Program or any
-    part thereof, to be licensed as a whole at no charge to all third
-    parties under the terms of this License.
-
-    c) If the modified program normally reads commands interactively
-    when run, you must cause it, when started running for such
-    interactive use in the most ordinary way, to print or display an
-    announcement including an appropriate copyright notice and a
-    notice that there is no warranty (or else, saying that you provide
-    a warranty) and that users may redistribute the program under
-    these conditions, and telling the user how to view a copy of this
-    License.  (Exception: if the Program itself is interactive but
-    does not normally print such an announcement, your work based on
-    the Program is not required to print an announcement.)
-
-These requirements apply to the modified work as a whole.  If
-identifiable sections of that work are not derived from the Program,
-and can be reasonably considered independent and separate works in
-themselves, then this License, and its terms, do not apply to those
-sections when you distribute them as separate works.  But when you
-distribute the same sections as part of a whole which is a work based
-on the Program, the distribution of the whole must be on the terms of
-this License, whose permissions for other licensees extend to the
-entire whole, and thus to each and every part regardless of who wrote it.
-
-Thus, it is not the intent of this section to claim rights or contest
-your rights to work written entirely by you; rather, the intent is to
-exercise the right to control the distribution of derivative or
-collective works based on the Program.
-
-In addition, mere aggregation of another work not based on the Program
-with the Program (or with a work based on the Program) on a volume of
-a storage or distribution medium does not bring the other work under
-the scope of this License.
-
-  3. You may copy and distribute the Program (or a work based on it,
-under Section 2) in object code or executable form under the terms of
-Sections 1 and 2 above provided that you also do one of the following:
-
-    a) Accompany it with the complete corresponding machine-readable
-    source code, which must be distributed under the terms of Sections
-    1 and 2 above on a medium customarily used for software interchange; or,
-
-    b) Accompany it with a written offer, valid for at least three
-    years, to give any third party, for a charge no more than your
-    cost of physically performing source distribution, a complete
-    machine-readable copy of the corresponding source code, to be
-    distributed under the terms of Sections 1 and 2 above on a medium
-    customarily used for software interchange; or,
-
-    c) Accompany it with the information you received as to the offer
-    to distribute corresponding source code.  (This alternative is
-    allowed only for noncommercial distribution and only if you
-    received the program in object code or executable form with such
-    an offer, in accord with Subsection b above.)
-
-The source code for a work means the preferred form of the work for
-making modifications to it.  For an executable work, complete source
-code means all the source code for all modules it contains, plus any
-associated interface definition files, plus the scripts used to
-control compilation and installation of the executable.  However, as a
-special exception, the source code distributed need not include
-anything that is normally distributed (in either source or binary
-form) with the major components (compiler, kernel, and so on) of the
-operating system on which the executable runs, unless that component
-itself accompanies the executable.
-
-If distribution of executable or object code is made by offering
-access to copy from a designated place, then offering equivalent
-access to copy the source code from the same place counts as
-distribution of the source code, even though third parties are not
-compelled to copy the source along with the object code.
-
-  4. You may not copy, modify, sublicense, or distribute the Program
-except as expressly provided under this License.  Any attempt
-otherwise to copy, modify, sublicense or distribute the Program is
-void, and will automatically terminate your rights under this License.
-However, parties who have received copies, or rights, from you under
-this License will not have their licenses terminated so long as such
-parties remain in full compliance.
-
-  5. You are not required to accept this License, since you have not
-signed it.  However, nothing else grants you permission to modify or
-distribute the Program or its derivative works.  These actions are
-prohibited by law if you do not accept this License.  Therefore, by
-modifying or distributing the Program (or any work based on the
-Program), you indicate your acceptance of this License to do so, and
-all its terms and conditions for copying, distributing or modifying
-the Program or works based on it.
-
-  6. Each time you redistribute the Program (or any work based on the
-Program), the recipient automatically receives a license from the
-original licensor to copy, distribute or modify the Program subject to
-these terms and conditions.  You may not impose any further
-restrictions on the recipients' exercise of the rights granted herein.
-You are not responsible for enforcing compliance by third parties to
-this License.
-
-  7. If, as a consequence of a court judgment or allegation of patent
-infringement or for any other reason (not limited to patent issues),
-conditions are imposed on you (whether by court order, agreement or
-otherwise) that contradict the conditions of this License, they do not
-excuse you from the conditions of this License.  If you cannot
-distribute so as to satisfy simultaneously your obligations under this
-License and any other pertinent obligations, then as a consequence you
-may not distribute the Program at all.  For example, if a patent
-license would not permit royalty-free redistribution of the Program by
-all those who receive copies directly or indirectly through you, then
-the only way you could satisfy both it and this License would be to
-refrain entirely from distribution of the Program.
-
-If any portion of this section is held invalid or unenforceable under
-any particular circumstance, the balance of the section is intended to
-apply and the section as a whole is intended to apply in other
-circumstances.
-
-It is not the purpose of this section to induce you to infringe any
-patents or other property right claims or to contest validity of any
-such claims; this section has the sole purpose of protecting the
-integrity of the free software distribution system, which is
-implemented by public license practices.  Many people have made
-generous contributions to the wide range of software distributed
-through that system in reliance on consistent application of that
-system; it is up to the author/donor to decide if he or she is willing
-to distribute software through any other system and a licensee cannot
-impose that choice.
-
-This section is intended to make thoroughly clear what is believed to
-be a consequence of the rest of this License.
-
-  8. If the distribution and/or use of the Program is restricted in
-certain countries either by patents or by copyrighted interfaces, the
-original copyright holder who places the Program under this License
-may add an explicit geographical distribution limitation excluding
-those countries, so that distribution is permitted only in or among
-countries not thus excluded.  In such case, this License incorporates
-the limitation as if written in the body of this License.
-
-  9. The Free Software Foundation may publish revised and/or new versions
-of the General Public License from time to time.  Such new versions will
-be similar in spirit to the present version, but may differ in detail to
-address new problems or concerns.
-
-Each version is given a distinguishing version number.  If the Program
-specifies a version number of this License which applies to it and "any
-later version", you have the option of following the terms and conditions
-either of that version or of any later version published by the Free
-Software Foundation.  If the Program does not specify a version number of
-this License, you may choose any version ever published by the Free Software
-Foundation.
-
-  10. If you wish to incorporate parts of the Program into other free
-programs whose distribution conditions are different, write to the author
-to ask for permission.  For software which is copyrighted by the Free
-Software Foundation, write to the Free Software Foundation; we sometimes
-make exceptions for this.  Our decision will be guided by the two goals
-of preserving the free status of all derivatives of our free software and
-of promoting the sharing and reuse of software generally.
-
-			    NO WARRANTY
-
-  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
-FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
-OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES

-	Appendix: How to Apply These Terms to Your New Programs
-
-  If you develop a new program, and you want it to be of the greatest
-possible use to the public, the best way to achieve this is to make it
-free software which everyone can redistribute and change under these terms.
-
-  To do so, attach the following notices to the program.  It is safest
-to attach them to the start of each source file to most effectively
-convey the exclusion of warranty; and each file should have at least
-the "copyright" line and a pointer to where the full notice is found.
-
-    <one line to give the program's name and a brief idea of what it does.>
-    Copyright (C) 19yy  <name of author>
-
-    This program is free software; you can redistribute it and/or modify
-    it under the terms of the GNU General Public License as published by
-    the Free Software Foundation; either version 2 of the License, or
-    (at your option) any later version.
-
-    This program is distributed in the hope that it will be useful,
-    but WITHOUT ANY WARRANTY; without even the implied warranty of
-    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
-    GNU General Public License for more details.
-
-    You should have received a copy of the GNU General Public License
-    along with this program; if not, write to the Free Software
-    Foundation, Inc., 675 Mass Ave, Cambridge, MA 02139, USA.
-
-Also add information on how to contact you by electronic and paper mail.
-
-If the program is interactive, make it output a short notice like this
-when it starts in an interactive mode:
-
-    Gnomovision version 69, Copyright (C) 19yy name of author
-    Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
-    This is free software, and you are welcome to redistribute it
-    under certain conditions; type `show c' for details.
-
-The hypothetical commands `show w' and `show c' should show the appropriate
-parts of the General Public License.  Of course, the commands you use may
-be called something other than `show w' and `show c'; they could even be
-mouse-clicks or menu items--whatever suits your program.
-
-You should also get your employer (if you work as a programmer) or your
-school, if any, to sign a "copyright disclaimer" for the program, if
-necessary.  Here is a sample; alter the names:
-
-  Yoyodyne, Inc., hereby disclaims all copyright interest in the program
-  `Gnomovision' (which makes passes at compilers) written by James Hacker.

-
-This General Public License does not permit incorporating your program into
-proprietary programs.  If your program is a subroutine library, you may
-consider it more useful to permit linking proprietary applications with the
-library.  If this is what you want to do, use the GNU Library General
-Public License instead of this License.

-		  GNU LIBRARY GENERAL PUBLIC LICENSE
-			 Version 2, June 1991
-
-	  Copyright (C) 1991 Free Software Foundation, Inc.
-       59 Temple Place, Suite 330, Boston, MA  02111-1307  USA
-
-     Everyone is permitted to copy and distribute verbatim copies
-      of this license document, but changing it is not allowed.
-
-    [This is the first released version of the library GPL.  It is
-   numbered 2 because it goes with version 2 of the ordinary GPL.]
-
-			       Preamble
-
-  The licenses for most software are designed to take away your
-freedom to share and change it.  By contrast, the GNU General Public
-Licenses are intended to guarantee your freedom to share and change
-free software--to make sure the software is free for all its users.
-
-  This license, the Library General Public License, applies to some
-specially designated Free Software Foundation software, and to any
-other libraries whose authors decide to use it.  You can use it for
-your libraries, too.
-
-  When we speak of free software, we are referring to freedom, not
-price.  Our General Public Licenses are designed to make sure that you
-have the freedom to distribute copies of free software (and charge for
-this service if you wish), that you receive source code or can get it
-if you want it, that you can change the software or use pieces of it
-in new free programs; and that you know you can do these things.
-
-  To protect your rights, we need to make restrictions that forbid
-anyone to deny you these rights or to ask you to surrender the rights.
-These restrictions translate to certain responsibilities for you if
-you distribute copies of the library, or if you modify it.
-
-  For example, if you distribute copies of the library, whether gratis
-or for a fee, you must give the recipients all the rights that we gave
-you.  You must make sure that they, too, receive or can get the source
-code.  If you link a program with the library, you must provide
-complete object files to the recipients so that they can relink them
-with the library, after making changes to the library and recompiling
-it.  And you must show them these terms so they know their rights.
-
-  Our method of protecting your rights has two steps: (1) copyright
-the library, and (2) offer you this license which gives you legal
-permission to copy, distribute and/or modify the library.
-
-  Also, for each distributor's protection, we want to make certain
-that everyone understands that there is no warranty for this free
-library.  If the library is modified by someone else and passed on, we
-want its recipients to know that what they have is not the original
-version, so that any problems introduced by others will not reflect on
-the original authors' reputations.
-
-  Finally, any free program is threatened constantly by software
-patents.  We wish to avoid the danger that companies distributing free
-software will individually obtain patent licenses, thus in effect
-transforming the program into proprietary software.  To prevent this,
-we have made it clear that any patent must be licensed for everyone's
-free use or not licensed at all.
-
-  Most GNU software, including some libraries, is covered by the ordinary
-GNU General Public License, which was designed for utility programs.  This
-license, the GNU Library General Public License, applies to certain
-designated libraries.  This license is quite different from the ordinary
-one; be sure to read it in full, and don't assume that anything in it is
-the same as in the ordinary license.
-
-  The reason we have a separate public license for some libraries is that
-they blur the distinction we usually make between modifying or adding to a
-program and simply using it.  Linking a program with a library, without
-changing the library, is in some sense simply using the library, and is
-analogous to running a utility program or application program.  However, in
-a textual and legal sense, the linked executable is a combined work, a
-derivative of the original library, and the ordinary General Public License
-treats it as such.
-
-  Because of this blurred distinction, using the ordinary General
-Public License for libraries did not effectively promote software
-sharing, because most developers did not use the libraries.  We
-concluded that weaker conditions might promote sharing better.
-
-  However, unrestricted linking of non-free programs would deprive the
-users of those programs of all benefit from the free status of the
-libraries themselves.  This Library General Public License is intended to
-permit developers of non-free programs to use free libraries, while
-preserving your freedom as a user of such programs to change the free
-libraries that are incorporated in them.  (We have not seen how to achieve
-this as regards changes in header files, but we have achieved it as regards
-changes in the actual functions of the Library.)  The hope is that this
-will lead to faster development of free libraries.
-
-  The precise terms and conditions for copying, distribution and
-modification follow.  Pay close attention to the difference between a
-"work based on the library" and a "work that uses the library".  The
-former contains code derived from the library, while the latter only
-works together with the library.
-
-  Note that it is possible for a library to be covered by the ordinary
-General Public License rather than by this special one.
-
-		  GNU LIBRARY GENERAL PUBLIC LICENSE
-   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
-
-  0. This License Agreement applies to any software library which
-contains a notice placed by the copyright holder or other authorized
-party saying it may be distributed under the terms of this Library
-General Public License (also called "this License").  Each licensee is
-addressed as "you".
-
-  A "library" means a collection of software functions and/or data
-prepared so as to be conveniently linked with application programs
-(which use some of those functions and data) to form executables.
-
-  The "Library", below, refers to any such software library or work
-which has been distributed under these terms.  A "work based on the
-Library" means either the Library or any derivative work under
-copyright law: that is to say, a work containing the Library or a
-portion of it, either verbatim or with modifications and/or translated
-straightforwardly into another language.  (Hereinafter, translation is
-included without limitation in the term "modification".)
-
-  "Source code" for a work means the preferred form of the work for
-making modifications to it.  For a library, complete source code means
-all the source code for all modules it contains, plus any associated
-interface definition files, plus the scripts used to control compilation
-and installation of the library.
-
-  Activities other than copying, distribution and modification are not
-covered by this License; they are outside its scope.  The act of
-running a program using the Library is not restricted, and output from
-such a program is covered only if its contents constitute a work based
-on the Library (independent of the use of the Library in a tool for
-writing it).  Whether that is true depends on what the Library does
-and what the program that uses the Library does.
-
-  1. You may copy and distribute verbatim copies of the Library's
-complete source code as you receive it, in any medium, provided that
-you conspicuously and appropriately publish on each copy an
-appropriate copyright notice and disclaimer of warranty; keep intact
-all the notices that refer to this License and to the absence of any
-warranty; and distribute a copy of this License along with the
-Library.
-
-  You may charge a fee for the physical act of transferring a copy,
-and you may at your option offer warranty protection in exchange for a
-fee.
-
-  2. You may modify your copy or copies of the Library or any portion
-of it, thus forming a work based on the Library, and copy and
-distribute such modifications or work under the terms of Section 1
-above, provided that you also meet all of these conditions:
-
-    a) The modified work must itself be a software library.
-
-    b) You must cause the files modified to carry prominent notices
-    stating that you changed the files and the date of any change.
-
-    c) You must cause the whole of the work to be licensed at no
-    charge to all third parties under the terms of this License.
-
-    d) If a facility in the modified Library refers to a function or a
-    table of data to be supplied by an application program that uses
-    the facility, other than as an argument passed when the facility
-    is invoked, then you must make a good faith effort to ensure that,
-    in the event an application does not supply such function or
-    table, the facility still operates, and performs whatever part of
-    its purpose remains meaningful.
-
-    (For example, a function in a library to compute square roots has
-    a purpose that is entirely well-defined independent of the
-    application.  Therefore, Subsection 2d requires that any
-    application-supplied function or table used by this function must
-    be optional: if the application does not supply it, the square
-    root function must still compute square roots.)
-
-These requirements apply to the modified work as a whole.  If
-identifiable sections of that work are not derived from the Library,
-and can be reasonably considered independent and separate works in
-themselves, then this License, and its terms, do not apply to those
-sections when you distribute them as separate works.  But when you
-distribute the same sections as part of a whole which is a work based
-on the Library, the distribution of the whole must be on the terms of
-this License, whose permissions for other licensees extend to the
-entire whole, and thus to each and every part regardless of who wrote
-it.
-
-Thus, it is not the intent of this section to claim rights or contest
-your rights to work written entirely by you; rather, the intent is to
-exercise the right to control the distribution of derivative or
-collective works based on the Library.
-
-In addition, mere aggregation of another work not based on the Library
-with the Library (or with a work based on the Library) on a volume of
-a storage or distribution medium does not bring the other work under
-the scope of this License.
-
-  3. You may opt to apply the terms of the ordinary GNU General Public
-License instead of this License to a given copy of the Library.  To do
-this, you must alter all the notices that refer to this License, so
-that they refer to the ordinary GNU General Public License, version 2,
-instead of to this License.  (If a newer version than version 2 of the
-ordinary GNU General Public License has appeared, then you can specify
-that version instead if you wish.)  Do not make any other change in
-these notices.
-
-  Once this change is made in a given copy, it is irreversible for
-that copy, so the ordinary GNU General Public License applies to all
-subsequent copies and derivative works made from that copy.
-
-  This option is useful when you wish to copy part of the code of
-the Library into a program that is not a library.
-
-  4. You may copy and distribute the Library (or a portion or
-derivative of it, under Section 2) in object code or executable form
-under the terms of Sections 1 and 2 above provided that you accompany
-it with the complete corresponding machine-readable source code, which
-must be distributed under the terms of Sections 1 and 2 above on a
-medium customarily used for software interchange.
-
-  If distribution of object code is made by offering access to copy
-from a designated place, then offering equivalent access to copy the
-source code from the same place satisfies the requirement to
-distribute the source code, even though third parties are not
-compelled to copy the source along with the object code.
-
-  5. A program that contains no derivative of any portion of the
-Library, but is designed to work with the Library by being compiled or
-linked with it, is called a "work that uses the Library".  Such a
-work, in isolation, is not a derivative work of the Library, and
-therefore falls outside the scope of this License.
-
-  However, linking a "work that uses the Library" with the Library
-creates an executable that is a derivative of the Library (because it
-contains portions of the Library), rather than a "work that uses the
-library".  The executable is therefore covered by this License.
-Section 6 states terms for distribution of such executables.
-
-  When a "work that uses the Library" uses material from a header file
-that is part of the Library, the object code for the work may be a
-derivative work of the Library even though the source code is not.
-Whether this is true is especially significant if the work can be
-linked without the Library, or if the work is itself a library.  The
-threshold for this to be true is not precisely defined by law.
-
-  If such an object file uses only numerical parameters, data
-structure layouts and accessors, and small macros and small inline
-functions (ten lines or less in length), then the use of the object
-file is unrestricted, regardless of whether it is legally a derivative
-work.  (Executables containing this object code plus portions of the
-Library will still fall under Section 6.)
-
-  Otherwise, if the work is a derivative of the Library, you may
-distribute the object code for the work under the terms of Section 6.
-Any executables containing that work also fall under Section 6,
-whether or not they are linked directly with the Library itself.
-
-  6. As an exception to the Sections above, you may also compile or
-link a "work that uses the Library" with the Library to produce a
-work containing portions of the Library, and distribute that work
-under terms of your choice, provided that the terms permit
-modification of the work for the customer's own use and reverse
-engineering for debugging such modifications.
-
-  You must give prominent notice with each copy of the work that the
-Library is used in it and that the Library and its use are covered by
-this License.  You must supply a copy of this License.  If the work
-during execution displays copyright notices, you must include the
-copyright notice for the Library among them, as well as a reference
-directing the user to the copy of this License.  Also, you must do one
-of these things:
-
-    a) Accompany the work with the complete corresponding
-    machine-readable source code for the Library including whatever
-    changes were used in the work (which must be distributed under
-    Sections 1 and 2 above); and, if the work is an executable linked
-    with the Library, with the complete machine-readable "work that
-    uses the Library", as object code and/or source code, so that the
-    user can modify the Library and then relink to produce a modified
-    executable containing the modified Library.  (It is understood
-    that the user who changes the contents of definitions files in the
-    Library will not necessarily be able to recompile the application
-    to use the modified definitions.)
-
-    b) Accompany the work with a written offer, valid for at
-    least three years, to give the same user the materials
-    specified in Subsection 6a, above, for a charge no more
-    than the cost of performing this distribution.
-
-    c) If distribution of the work is made by offering access to copy
-    from a designated place, offer equivalent access to copy the above
-    specified materials from the same place.
-
-    d) Verify that the user has already received a copy of these
-    materials or that you have already sent this user a copy.
-
-  For an executable, the required form of the "work that uses the
-Library" must include any data and utility programs needed for
-reproducing the executable from it.  However, as a special exception,
-the source code distributed need not include anything that is normally
-distributed (in either source or binary form) with the major
-components (compiler, kernel, and so on) of the operating system on
-which the executable runs, unless that component itself accompanies
-the executable.
-
-  It may happen that this requirement contradicts the license
-restrictions of other proprietary libraries that do not normally
-accompany the operating system.  Such a contradiction means you cannot
-use both them and the Library together in an executable that you
-distribute.
-
-  7. You may place library facilities that are a work based on the
-Library side-by-side in a single library together with other library
-facilities not covered by this License, and distribute such a combined
-library, provided that the separate distribution of the work based on
-the Library and of the other library facilities is otherwise
-permitted, and provided that you do these two things:
-
-    a) Accompany the combined library with a copy of the same work
-    based on the Library, uncombined with any other library
-    facilities.  This must be distributed under the terms of the
-    Sections above.
-
-    b) Give prominent notice with the combined library of the fact
-    that part of it is a work based on the Library, and explaining
-    where to find the accompanying uncombined form of the same work.
-
-  8. You may not copy, modify, sublicense, link with, or distribute
-the Library except as expressly provided under this License.  Any
-attempt otherwise to copy, modify, sublicense, link with, or
-distribute the Library is void, and will automatically terminate your
-rights under this License.  However, parties who have received copies,
-or rights, from you under this License will not have their licenses
-terminated so long as such parties remain in full compliance.
-
-  9. You are not required to accept this License, since you have not
-signed it.  However, nothing else grants you permission to modify or
-distribute the Library or its derivative works.  These actions are
-prohibited by law if you do not accept this License.  Therefore, by
-modifying or distributing the Library (or any work based on the
-Library), you indicate your acceptance of this License to do so, and
-all its terms and conditions for copying, distributing or modifying
-the Library or works based on it.
-
-  10. Each time you redistribute the Library (or any work based on the
-Library), the recipient automatically receives a license from the
-original licensor to copy, distribute, link with or modify the Library
-subject to these terms and conditions.  You may not impose any further
-restrictions on the recipients' exercise of the rights granted herein.
-You are not responsible for enforcing compliance by third parties to
-this License.
-
-  11. If, as a consequence of a court judgment or allegation of patent
-infringement or for any other reason (not limited to patent issues),
-conditions are imposed on you (whether by court order, agreement or
-otherwise) that contradict the conditions of this License, they do not
-excuse you from the conditions of this License.  If you cannot
-distribute so as to satisfy simultaneously your obligations under this
-License and any other pertinent obligations, then as a consequence you
-may not distribute the Library at all.  For example, if a patent
-license would not permit royalty-free redistribution of the Library by
-all those who receive copies directly or indirectly through you, then
-the only way you could satisfy both it and this License would be to
-refrain entirely from distribution of the Library.
-
-If any portion of this section is held invalid or unenforceable under any
-particular circumstance, the balance of the section is intended to apply,
-and the section as a whole is intended to apply in other circumstances.
-
-It is not the purpose of this section to induce you to infringe any
-patents or other property right claims or to contest validity of any
-such claims; this section has the sole purpose of protecting the
-integrity of the free software distribution system which is
-implemented by public license practices.  Many people have made
-generous contributions to the wide range of software distributed
-through that system in reliance on consistent application of that
-system; it is up to the author/donor to decide if he or she is willing
-to distribute software through any other system and a licensee cannot
-impose that choice.
-
-This section is intended to make thoroughly clear what is believed to
-be a consequence of the rest of this License.
-
-  12. If the distribution and/or use of the Library is restricted in
-certain countries either by patents or by copyrighted interfaces, the
-original copyright holder who places the Library under this License may add
-an explicit geographical distribution limitation excluding those countries,
-so that distribution is permitted only in or among countries not thus
-excluded.  In such case, this License incorporates the limitation as if
-written in the body of this License.
-
-  13. The Free Software Foundation may publish revised and/or new
-versions of the Library General Public License from time to time.
-Such new versions will be similar in spirit to the present version,
-but may differ in detail to address new problems or concerns.
-
-Each version is given a distinguishing version number.  If the Library
-specifies a version number of this License which applies to it and
-"any later version", you have the option of following the terms and
-conditions either of that version or of any later version published by
-the Free Software Foundation.  If the Library does not specify a
-license version number, you may choose any version ever published by
-the Free Software Foundation.
-
-  14. If you wish to incorporate parts of the Library into other free
-programs whose distribution conditions are incompatible with these,
-write to the author to ask for permission.  For software which is
-copyrighted by the Free Software Foundation, write to the Free
-Software Foundation; we sometimes make exceptions for this.  Our
-decision will be guided by the two goals of preserving the free status
-of all derivatives of our free software and of promoting the sharing
-and reuse of software generally.
-
-			    NO WARRANTY
-
-  15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
-WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
-EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
-OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
-KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
-IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
-PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
-LIBRARY IS WITH YOU.  SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
-THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
-
-  16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
-WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
-AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
-FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
-CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
-LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
-RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
-FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
-SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
-DAMAGES.
-
-		     END OF TERMS AND CONDITIONS
-
-     Appendix: How to Apply These Terms to Your New Libraries
-
-  If you develop a new library, and you want it to be of the greatest
-possible use to the public, we recommend making it free software that
-everyone can redistribute and change.  You can do so by permitting
-redistribution under these terms (or, alternatively, under the terms of the
-ordinary General Public License).
-
-  To apply these terms, attach the following notices to the library.  It is
-safest to attach them to the start of each source file to most effectively
-convey the exclusion of warranty; and each file should have at least the
-"copyright" line and a pointer to where the full notice is found.
-
-    <one line to give the library's name and a brief idea of what it does.>
-    Copyright (C) <year>  <name of author>
-
-    This library is free software; you can redistribute it and/or
-    modify it under the terms of the GNU Library General Public
-    License as published by the Free Software Foundation; either
-    version 2 of the License, or (at your option) any later version.
-
-    This library is distributed in the hope that it will be useful,
-    but WITHOUT ANY WARRANTY; without even the implied warranty of
-    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the GNU
-    Library General Public License for more details.
-
-    You should have received a copy of the GNU Library General Public
-    License along with this library; if not, write to the Free
-    Software Foundation, Inc., 675 Mass Ave, Cambridge, MA 02139, USA.
-
-Also add information on how to contact you by electronic and paper mail.
-
-You should also get your employer (if you work as a programmer) or your
-school, if any, to sign a "copyright disclaimer" for the library, if
-necessary.  Here is a sample; alter the names:
-
-  Yoyodyne, Inc., hereby disclaims all copyright interest in the
-  library `Frob' (a library for tweaking knobs) written by James Random Hacker.

+README - CUPS v2.3.3 - 2020-04-24
+=================================
+
+INTRODUCTION
+------------
+
+CUPS is a standards-based, open source printing system developed by Apple Inc.
+for macOS® and other UNIX®-like operating systems.  CUPS uses the Internet
+Printing Protocol ("IPP") and provides System V and Berkeley command-line
+interfaces, a web interface, and a C API to manage printers and print jobs.  It
+supports printing to both local (parallel, serial, USB) and networked printers,
+and printers can be shared from one computer to another, even over the Internet!
+
+Internally, CUPS uses PostScript Printer Description ("PPD") files to describe
+printer capabilities and features and a wide variety of generic and device-
+specific programs to convert and print many types of files.  Sample drivers are
+included with CUPS to support many Dymo, EPSON, HP, Intellitech, OKIDATA, and
+Zebra printers.  Many more drivers are available online and (in some cases) on
+the driver CD-ROM that came with your printer.
+
+CUPS is licensed under the Apache License Version 2.0.  See the file
+"LICENSE" for more information.
+
+
+READING THE DOCUMENTATION
+-------------------------
+
+Initial documentation to get you started is provided in the root directory of
+the CUPS sources:
+
+- `CHANGES.md`: A list of changes in the current major release of CUPS.
+- `CONTRIBUTING.md`: Guidelines for contributing to the CUPS project.
+- `CREDITS.md`: A list of past contributors to the CUPS project.
+- `DEVELOPING.md`: Guidelines for developing code for the CUPS project.
+- `INSTALL.md`: Instructions for building and installing CUPS.
+- `LICENSE`: The CUPS license agreement (Apache 2.0).
+- `NOTICE`: Copyright notices and exceptions to the CUPS license agreement.
+- `README.md`: This file.
+
+Once you have installed the software you can access the documentation (and a
+bunch of other stuff) online at <http://localhost:631/> and using the `man`
+command, for example `man cups`.
+
+If you're having trouble getting that far, the documentation is located under
+the `doc/help` and `man` directories.
+
+Please read the documentation before asking questions.
+
+
+GETTING SUPPORT AND OTHER RESOURCES
+-----------------------------------
+
+If you have problems, *read the documentation first!*  We also provide two
+mailing lists which are available at <https://lists.cups.org/mailman/listinfo>.
+
+See the CUPS web site at <https://www.cups.org/> for other resources.
+
+
+SETTING UP PRINTER QUEUES USING YOUR WEB BROWSER
+------------------------------------------------
+
+CUPS includes a web-based administration tool that allows you to manage
+printers, classes, and jobs on your server.  Open <http://localhost:631/admin/>
+in your browser to access the printer administration tools:
+
+*Do not* use the hostname for your machine - it will not work with the default
+CUPS configuration.  To enable administration access on other addresses, check
+the `Allow Remote Administration` box and click on the `Change Settings` button.
+
+You will be asked for the administration password (root or any other user in the
+"sys", "system", "root", "admin", or "lpadmin" group on your system) when
+performing any administrative function.
+
+
+SETTING UP PRINTER QUEUES FROM THE COMMAND-LINE
+-----------------------------------------------
+
+CUPS currently uses PPD (PostScript Printer Description) files that describe
+printer capabilities and driver programs needed for each printer.  The
+`everywhere` PPD is used for nearly all modern networks printers sold since
+about 2009.  For example, the following command creates a print queue for a
+printer at address "11.22.33.44":
+
+    lpadmin -p printername -E -v ipp://11.22.33.44/ipp/print -m everywhere
+
+CUPS also includes several sample PPD files you can use for "legacy" printers:
+
+   Driver                         | PPD Name
+   -----------------------------  | ------------------------------
+   Dymo Label Printers            | drv:///sample.drv/dymo.ppd
+   Intellitech Intellibar         | drv:///sample.drv/intelbar.ppd
+   EPSON 9-pin Series             | drv:///sample.drv/epson9.ppd
+   EPSON 24-pin Series            | drv:///sample.drv/epson24.ppd
+   Generic PCL Laser Printer      | drv:///sample.drv/generpcl.ppd
+   Generic PostScript Printer     | drv:///sample.drv/generic.ppd
+   HP DeskJet Series              | drv:///sample.drv/deskjet.ppd
+   HP LaserJet Series             | drv:///sample.drv/laserjet.ppd
+   OKIDATA 9-Pin Series           | drv:///sample.drv/okidata9.ppd
+   OKIDATA 24-Pin Series          | drv:///sample.drv/okidat24.ppd
+   Zebra CPCL Label Printer       | drv:///sample.drv/zebracpl.ppd
+   Zebra EPL1 Label Printer       | drv:///sample.drv/zebraep1.ppd
+   Zebra EPL2 Label Printer       | drv:///sample.drv/zebraep2.ppd
+   Zebra ZPL Label Printer        | drv:///sample.drv/zebra.ppd
+
+You can run the `lpinfo -m` command to list all of the available drivers:
+
+    lpinfo -m
+
+Run the `lpinfo -v` command to list the available printers:
+
+    lpinfo -v
+
+Then use the correct URI to add the printer using the `lpadmin` command:
+
+    lpadmin -p printername -E -v device-uri -m ppd-name
+
+Current network printers typically use `ipp` or `ipps` URIS:
+
+    lpadmin -p printername -E -v ipp://11.22.33.44/ipp/print -m everywhere
+    lpadmin -p printername -E -v ipps://11.22.33.44/ipp/print -m everywhere
+
+Older network printers typically use `socket` or `lpd` URIs:
+
+    lpadmin -p printername -E -v socket://11.22.33.44 -m ppd-name
+    lpadmin -p printername -E -v lpd://11.22.33.44/ -m ppd-name
+
+The sample drivers provide basic printing capabilities, but generally do not
+exercise the full potential of the printers or CUPS.  Other drivers provide
+greater printing capabilities.
+
+
+PRINTING FILES
+--------------
+
+CUPS provides both the System V `lp` and Berkeley `lpr` commands for printing:
+
+    lp filename
+    lpr filename
+
+Both the `lp` and `lpr` commands support printing options for the driver:
+
+    lp -o media=A4 -o resolution=600dpi filename
+    lpr -o media=A4 -o resolution=600dpi filename
+
+CUPS recognizes many types of images files as well as PDF, PostScript, and text
+files, so you can print those files directly rather than through an application.
+
+If you have an application that generates output specifically for your printer
+then you need to use the `-oraw` or `-l` options:
+
+    lp -o raw filename
+    lpr -l filename
+
+This will prevent the filters from misinterpreting your print file.

-
-GETTING SUPPORT AND OTHER RESOURCES
-
-    If you have problems, READ THE DOCUMENTATION FIRST!  We also provide two
-    mailing lists which are available at:
-
-	http://www.cups.org/lists.php
-
-    See the CUPS web site at "http://www.cups.org/" for other resources.

-SETTING UP PRINTER QUEUES USING YOUR WEB BROWSER
-
-    CUPS includes a web-based administration tool that allows you to manage
-    printers, classes, and jobs on your server.  Open the following URL in your
-    browser to access the printer administration tools:
-
-	http://localhost:631/admin/
-
-    DO NOT use the hostname for your machine - it will not work with the default
-    CUPS configuration.  To enable administration access on other addresses,
-    check the "Allow Remote Administration" box and click on the "Change
-    Settings" button.
-
-    You will be asked for the administration password (root or any other user in
-    the sys/system/root/admin/lpadmin group on your system) when performing any
-    administrative function.
-
-
-SETTING UP PRINTER QUEUES FROM THE COMMAND-LINE
-
-    CUPS works best with PPD (PostScript Printer Description) files.  In a pinch
-    you can also use System V style printer interface scripts.
-
-    CUPS includes several sample PPD files you can use:
-
-	Driver                         PPD Name
-	-----------------------------  ------------------------------
-	Dymo Label Printers            drv:///sample.drv/dymo.ppd
-	Intellitech Intellibar         drv:///sample.drv/intelbar.ppd
-	EPSON 9-pin Series             drv:///sample.drv/epson9.ppd
-	EPSON 24-pin Series            drv:///sample.drv/epson24.ppd
-	Generic PCL Laser Printer      drv:///sample.drv/generpcl.ppd
-	Generic PostScript Printer     drv:///sample.drv/generic.ppd
-	HP DeskJet Series              drv:///sample.drv/deskjet.ppd
-	HP LaserJet Series             drv:///sample.drv/laserjet.ppd
-	OKIDATA 9-Pin Series           drv:///sample.drv/okidata9.ppd
-	OKIDATA 24-Pin Series          drv:///sample.drv/okidat24.ppd
-	Zebra CPCL Label Printer       drv:///sample.drv/zebracpl.ppd
-	Zebra EPL1 Label Printer       drv:///sample.drv/zebraep1.ppd
-	Zebra EPL2 Label Printer       drv:///sample.drv/zebraep2.ppd
-	Zebra ZPL Label Printer        drv:///sample.drv/zebra.ppd
-
-    Run the "lpinfo -m" command to list the available drivers:
-
-        lpinfo -m
-
-    Run the "lpinfo -v" command to list the available printers:
-
-        lpinfo -v
-
-    Then use the correct URI to add the printer using the "lpadmin" command:
-
-        lpadmin -p printername -E -v device-uri -m ppd-name
-
-    Network printers typically use "socket" or "lpd" URIs:
-
-        lpadmin -p printername -E -v socket://11.22.33.44 -m ppd-name
-        lpadmin -p printername -E -v lpd://11.22.33.44/ -m ppd-name
-
-    The sample drivers provide basic printing capabilities, but generally do not
-    exercise the full potential of the printers or CUPS.
-
-
-PRINTING FILES
-
-    CUPS provides both the System V "lp" and Berkeley "lpr" commands for
-    printing:
-
-	lp filename
-	lpr filename
-
-    Both the "lp" and "lpr" commands support printing options for the driver:
-
-	lp -o media=A4 -o resolution=600dpi filename
-	lpr -o media=A4 -o resolution=600dpi filename
-
-    CUPS recognizes many types of images files as well as PDF, PostScript,
-    and text files, so you can print those files directly rather than through
-    an application.
-
-    If you have an application that generates output specifically for your
-    printer then you need to use the "-oraw" or "-l" options:
-
-	lp -o raw filename
-	lpr -l filename
-
-    This will prevent the filters from misinterpreting your print file.
-
