infobot

    A bot that serves as a common database of information
   (often noteworthy URLs) for users on a chat system.
   Infobots often have a simple chatbot interface, responding
   to key-phrases, as well as to direct queries.

   Here, in a real conversation, the bot Purl's first response is
   triggered by the phrase "just tell me", and its second
   response is triggered by being directly asked "perlfunc?":

     can someone tell me what: $num9 =
           substr($number,9,1); means

     eesh -- man perlfunc, look at "substr".

     just tell me

     Didn't your momma ever tell you, "Go
           look it up in the dictionary"?!

     eesh -- no.  that's all we'll tell
           you.  read the documentation.

     eesh -- if you haven't man pages or
           perldoc, you can read them on the 'net.

     purl, perlfunc?

     well, perlfunc is Perl builtin
           functions, at man perlfunc or
           http://perl.com/CPAN-local/doc/manual/html/pod/perlfunc.html
