=head1 NAME

AxKit::XSP::MD5 - AxKit XSP taglib for MD5 digests

=head1 SYNOPSIS

Add the md5 namespace to your XSP C<> tag:


    language='Perl'
    xmlns:xsp='http://apache.org/xsp/core/v1'
    xmlns:md5='http://xmlns.knowscape.com/xsp/MD5'>

And add the taglib to AxKit (via httpd.conf or .htaccess):

  AxAddXSPTaglib AxKit::XSP::MD5

=head1 DESCRIPTION

The XSP MD5 taglib implements MD5 digests (as provided by the
Digest::MD5 module). You may use it to generate keys for cookies or
checksums for files (if there is demand for this, I'll implement
MD5'ing an external file).

=head2 Tag Reference

There are three tags provided by this taglib, which map to
Digest::MD5's three functions: md5:md5, md5:md5-hex, md5:md5-base64.
Please refer to Digest::MD5's documentation for these. The data is
quite simply the content of the tags.
