%description
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 mod_php.
