 # Written to use 'curl' for URL checking.
 #
 # Author: Daniel Stenberg <daniel@haxx.se>
-# Version: 0.1 Dec 14, 2000
+# Version: 0.2 Dec 19, 2000
 #
 # HISTORY
 #
+# 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.
+#
 # 0.1 - The given url works as the root. This script will only continue
 #       and check other URLs if the leftmost part of the new URL is identical
 #       to the root URL.
