# This sample shell script can be used to start and stop
# external processes at the beginning and ending of the
# sfs load generation period respectively. The name of
# this program is pased in via the PRIME_MON_SCRIPT variable
# in the sfs_rc or equivalent file. The sfs_prime program
# executes this shell script just before it issues the START
# message to all the clients ie. "script_name START"; and likewise
# another call after all the clients have completed load generation ie.
# "script_name DONE".
#
# All environment variables exported from sfs_mgr are available for use.
