Motivation
----------
Seen GNU 'parallel' and 'pssh', 'mssh'. I wanted something written
in plain C for managing my RaspberryPi cluster.
Other tools
-----------
PSsh
----
http://code.google.com/p/parallel-ssh/
PSsh is Python, startup time of Python is not fast, especially not
on a Rasperry Pi B serving as master of a Pi cluster. :-)
Pssh has very nice tools and usage, we will try to copy from there.
Pssh writes output files into directories, this is a nice feature,
but I think it should be optional not mandatory and the default should
be stdout/stderr.
Pssh shows results at the very end, I want to be able to monitor
progress of the commands being executed.
GNU parallel
------------
Way complex, good for batches. I think cssh should not try to compete
with it. GNU parallel is written in Perl.
Why libssh and not libssh2
--------------------------
Not a clue, really. I think both are nice libraries.

GNU parallel: very nice and powerfull, we want something simpler.
