+# PLATFORM: AIX Only
+#
+# 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

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