Create a directed graph of processes and pipes
pipexec creates an arbitrary network (directed graph) of processes and pipes in between - even cycles are possible. It overcomes the short comings of shells that are typically only able to create non cyclic trees.
pipexec also monitors all its child processes and is able to restart the whole network of processes and pipes if one crashes. Therefore pipexec can be used in SYSV-init or systemd configuration to run a network of processes.
The package also contains two tools 'ptee' and 'peet' which are the piped version of the 'tee' and 'eet' (reverse tee) commands.
