pipexec - 2.6.1-3 main

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.
