DESCRIPTION
   Apache::AntiSpam is a filter module to prevent e-mail addresses exposed
   as is on web pages. The way to hide addresses from spammers are
   implemented in each of Apache::Antispam::* subclasses.

   This module is Filter aware, meaning that it can work within
   Apache::Filter framework without modification.

SUBCLASSING
   Here is how to make your own filter.

   Declare your class
   Inherit from Apache::AntiSpam
   define antispamize() method
   That's all. Template of antispamize() method will be like this:

     sub antispamize {
         my($class, $email, $orig) = @_;
         # do some stuff..
         return $orig;
     }

   where "$class" is your class, "$email" is an instance of Mail::Address,
   and "$orig" is an original e-mail address string. See the Email::Find
   manpage for details.

TODO
   *   remove mailto: tags using HTML::Parser.

ACKNOWLEDGEMENTS
   The idea of this module is stolen from Apache::AddrMunge by Mark J
   Dominus. See http://perl.plover.com/AddrMunge/ for details.

   Many thanks to Michael G. Schwern for kindly improving the matching
   speed of Email::Find.
