# Used as a standard client cmd that can be used for many of the xcat cmds.
# It grabs the arguments, noderange, and stdin and then submits the request to
# xcatd and waits for responses.  Most of the client/server communication is
# contained in Client.pm.

# To use this, sym link your cmd name to this script.
