# This is an example proposed Puppet Common Module for SSH
#
# Usage Requirements:
# 1) Set $server in site.pp
#    Allows for a different fileserver than the real puppetmaster
# 2) Set $os to $operatingsystem
#    Saves typing, purely cosmetic
# 3) Set $osver to $operatingsystemrelease or $lsbdistrelease
#    $operatingsystemrelease is not available on all platforms
#
