+# PURPOSE: This shell script is used to produce a report of
+#        the system's paging space statistics including:
+#
+#     Total paging space in MB, MB of Free paging space,
+#     MB of Used paging space, % of paging space Used, and
+#     % of paging space Free

+# REV LIST:

+# set -x # Uncomment to debug this shell script
+# set -n # Uncomment to check command syntax without any execution
