+# This script extracts all links from a HTML page and checks their validity.
+# Written to use 'curl' for URL checking.
+#
+# Author: Daniel Stenberg <Daniel.Stenberg@sth.frontec.se>
+# Version: 0.7 Sept 30, 1998
+#
+# HISTORY
+#
+# 0.5 - Cuts off the #-part from links before checking.
+#
+# 0.6 - Now deals with error codes 3XX better and follows the Location:
+#       properly.
+#     - Added the -x flag that only checks http:// -links
+#
+# 0.7 - Ok, http://www.viunga.se/main.html didn't realize this had no path
+#       but a document. Now it does.

+# crawlink.pl
+#
+# This script crawls across all found links below the given "root" URL.
+# It reports all good and bad links to stdout. This code was based on the
+# checklink.pl script I wrote ages ago.
+#
+# Written to use 'curl' for URL checking.
+#
+# Author: Daniel Stenberg <daniel@haxx.se>
+# 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.
+#
+# 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.
