#@(#) smb-wall.pl Description:
#@(#) A perl script which allows you to announce whatever you choose to
#@(#) every PC client currently connected to a Samba Server...
#@(#) ...using "smbclient -M" message to winpopup service.
#@(#) Default usage is to message every connected PC.
#@(#) Alternate usage is to message every pc on the argument list.
#@(#) Hacked up by Keith Farrar <farrar@parc.xerox.com>
#
# Cleanup and corrections by
# Michal Jaegermann <michal@ellpspace.math.ualberta.ca>
# Message to send can be now also fed (quietly) from stdin; a pipe will do.
#=============================================================================
