+
+=head1 DESCRIPTION
+
+This program checks that all the URLs in the Perl source are valid. It
+checks HTTP and FTP links in parallel and contains a list of known
+bad example links in its source. It takes 4 minutes to run on my
+machine. The results are written to 'uris.txt' and list the filename,
+the URL and the error:
+
+  * ext/Locale-Maketext/lib/Locale/Maketext.pod
+    http://sunsite.dk/RFC/rfc/rfc2277.html
+      404 Not Found
+  ...
+
+It should be run every so often and links fixed and upstream authors
+notified.
+
+Note that the web is unstable and some websites are temporarily down.
