php-symfony-process binary package in Ubuntu Lunar s390x

 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.
