我希望这样的输出只能回答。

   CPAN Search is a search engine for the distributions, modules, docs, and ID's on CPAN. It was conceived and built by Graham Barr as a way to make things easier to navigate. Originally named TUCS [ The Ultimate CPAN Search ] it was later named CPAN Search or Search DOT CPAN.

   If you are having technical difficulties with the site itself, send mail to cpansearch@perl.org and try to be as detailed as possible in your note describing the problem.
