#NAME
#     osirisStartGuis -- Start the OSIRIS observing GUIs
#
#SYNOPSIS
#     osirisStartGuis [-t #] [-m] etc...
#
#DESCRIPTION
#     Called via a pulldown or from osirisSetupNight to start GUIs
#
#OPTIONS
#     -t #
#          ID number to attach to all script generated errors, warnings, and
#          questions that are passed to the OGS.  The ID number is separated
#          from the rest of the message with a ";".
#
#     -m
#          simulate calls to RPC servers.  during simulated calls, the
