+# SCRIPT: AIXsysconfig.ksh
+#
+# AUTHOR: Randy Michael
+# REV: 2.1.A
+# DATE: 06/14/2007
+#
+# PLATFORM: AIX only
+#
+# PURPOSE:  Take a snapshot of the system for later comparision in the
+# 	    event of system problems. All data is stored in 
+#           /usr/local/reboot in the file defined to the $SYSINFO_FILE
+#           variable below.
+#
+#
+# REV LIST:
+#           7/11/2007: Changed this script to use a single output file
+#                      that receives data from a series of commands
+#                      within a bunch of functions.
+#
+#           10/11/2007: Added the following commands to capture 
+#                      the AIX technology level and patch set, and
+#                      print the system configuration
+#
+#                      oslevel -s   # Show TL and patch levels
+#
+#                      prtconf  # Print the system configuration
+#

+#
+# set -x  # Uncomment to debug this script
+# set -n  # Uncomment to verify command syntax without execution
