 # Written to use 'curl' for URL checking.

-# Version: 0.2 Dec 19, 2000
+# Version: 0.3 Jan 3, 2001
 #
 # HISTORY
 #
+# 0.3 - The -i now adds regexes that if a full URL link matches one of those,
+#       it is not followed. This can then be used to prevent this script from
+#       following '.*\.cgi', specific pages or whatever.
+#
 # 0.2 - Made it only HEAD non html files (i.e skip the GET). Makes it a lot
 #       faster to skip large non HTML files such as pdfs or big RFCs! ;-)
 #       Added a -c option that allows me to pass options to curl.
