Currently the debugger config file is always expected to be at ~/.hphpd.hdf, except when the debugger is controlled via the API, in which case the API client can specify the path. With these changes the path can now also be specified via the command line. Also, the test runner has been modified to look for an hphpd.hdf file and specify the path to it as a command line option. If present, this file also indicates that tests in the directory must be run in debugger mode, making the .opt files redundant. Note that it is important for tests to be able to control the contents of the config file since debugger output is controlled by it and tests will be brittle unless the config is part of the suite and not controlled by the user running the tests
HipHop VM for PHP 
HipHop VM (HHVM) is a new open-source virtual machine designed for executing programs written in PHP. HHVM uses a just-in-time compilation approach to achieve superior performance while maintaining the flexibility that PHP developers are accustomed to. HipHop VM (and before it HPHPc) has realized > 5x increase in throughput for Facebook compared with Zend PHP 5.2.
HipHop is most commonly run as a standalone server, replacing both Apache and modphp.
Installing
You can install a prebuilt package or compile from source.
Running
You can run standalone programs just by passing them to hhvm: hhvm my_script.php.
HipHop bundles in a webserver. So if you want to run on port 80 in the current directory:
sudo hhvm -m server
For anything more complicated, you'll want to make a config.hdf and run sudo hhvm -m server -c config.hdf.
Contributing
We'd love to have your help in making HipHop better. If you run into problems, please open an issue, or better yet, fork us and send a pull request. Join us on #hhvm on freenode.
If you want to help but don't know where to start, try fixing some of the Zend tests that don't pass. You can run them with hphp/test/run. When they work, move them to zend/good and send a pull request.
