#    1. Uagent v3.0 (supports ARCserve/Open)
#
# Date: 08/06/93 (JH)
#    1. add a flag to specify Follow_Symbolic_Link or not, which is
#       determined by the existence of file $UAGBIN/uagent/follow.symlink.
#
# Usage: uagent [start [-p <tcp port#>] [follow] | stop | status | follow | notfollow]
#
# Date: 9/28/92 (JH)
#    1. change 'arcagent' to 'uagentd'
#    2. path for 'uagentd' ($UAGBIN) is determined at installation
#
# Date: 4/19/92 (PL)
#
#menu# uagent [start [-p <tcp port#>] | stop | status]
#help# start will start UAGENT.
#help# stop will stop UAGENT.
#help# status will tell you if UAGENT is running.
