The Symfony Process 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.
