+# This is an applicaton of Marcus Ranum's principal of "Artificial Ignorance"
+# http://www.ranum.com/security/computer_security/papers/ai/
+#
+# Usage: ai input-file term1 [term2 ...]
+#
+#   Input:
+#      - input-file on the command line
+#      - terms - one or more on the command line.
+#
+#                terms can have "|" to match more than one term.
+#
+#                If there is a "|", the first term will be used
+#                as the output file name.
+#
+#                Note if you want the
+#                output to have a particualr name, use it as
+#                the first term, it may not actually match in grep.
+#
+#   Output:
+#      - ai-TERM1.txt
+#      - ai-TERM2.txt
+#      - ...
+#      - ai-TERMn.txt
