#NAME
#     osirisGetSetnum
#
#SYNOPSIS
#     osirisGetSetnum IMAG|SPEC [-t #] [-m] 
#
#DESCRIPTION
#     Returns the current set number based upon the data directories.
#	Useful for recovering detector server crashes.  Normally, the 
#       set number is returned to 0 upon a restart which can confuse
#       the data directories.
#
#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 
#          command is echoed (instead of being executed).
