php-symfony-process 2.3.19-2 (amd64 binary) in ubuntu vivid

 This Symfony Component helps with executing commands in sub-processes by
 providing easy access to standard and error output in real-time. It is
 especially handy for dealing with long running sub-processes due to its
 feature to run them asynchronously, while still providing access to their
 full and incremental output. It additionally supports signals, provides
 the PID of a sub-process and allows the definition of process timeouts.

 Symfony is a PHP framework, a set of tools and a development
 methodology.
