+# SCRIPT: chpwd_menu.ksh
+# AUTHOR: Randy Michael
+# DATE: 11/05/2007
+# PLATFORM: AIX
+# REV: 1.1.P
+#
+# PURPOSE: This script was created for the Operations Team
+#          to change user passwords. This shell script uses
+#          "sudo" to execute the "pwdadm" command as root.
+#          Each member of the Operations Team needs to be
+#          added to the /etc/sudoers file. CAUTION: When
+#          editing the /etc/sudoers file always use the
+#          /usr/local/sbin/visudo program editor!!!
+#          NEVER DIRECTLY EDIT THE sudoers FILE!!!!
+#
+# REV LIST:
+#
+#
+# set -x # Uncomment to debug this script
+# set -n # Uncomment to check syntax without any execution
