A parameter completion wrapper for (t)csh. It can be called from the built-in csh complete command
#!/usr/bin/env ruby
#
# This is a wrapper to query the appropiate command/parameter
# completions for (t)csh.
#
# Armin Widegreen (c) 2013
#
# A call returns a space-seperated string
# of the possible completions, e.g.:
# ParameterCompletion.getCompletionString("cmd1 diff")
