+# 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.
