ABOUT

       This script is designed to receive a filename and a global formatting type upon the
       command line.  The formatting type specifies how the blog entry file will be processed:

         1.  If the format is "textile" the file will be converted from textile
            to HTML.

         2.  If the format is "markdown" the file will be converted from markdown
            to HTML.  The related format "multimarkdown" is also recognised.

         3.  If the format is "html" no changes will be made.

       Once the conversion has been applied the code will also be scanned for <code> tags to
       expand via the Text::VimColour module, if it is installed, which allows the pretty-
       printing of source code.

       To enable the syntax highlighting of code fragments you should format your code samples as
       follows:

          Subject: Some highlighted code.
          Date: 25th December 2009
          Tags: chronicle, perl, blah

          <p>Here is some code which will look pretty ..</p>
          <code lang="perl">
          #!/usr/bin/perl -w
          ...
          ..
          </code>

       Notice the use of lang="perl", which provides a hint as to the type of syntax highlighting
       to apply.

       Additionally you may make use of the pre-filter and post-filter pseudo-headers which allow
       you to transform the entry in further creative fashions.

       For example you might wish the blog to be upper-case only for some reason, and this could
       be achieved via:

         Subject: I DONT LIKE LOWER CASE
         Tags: meta, random, silly
         Date: 25th December 2009
         Pre-Filter: perl -pi -e "s/__USER__/`whoami`/g"
         Post-filter: tr [a-z] [A-Z]

         <p>This post, written by __USER__ will have no lower-case values.</p>
         <p>Notice how my username was inserted too?</p>

       You may chain arbitrarily complex filters together via the filters.  Each filter should
       read the entry on STDIN and return the updated content to STDOUT.

       (If you wish to apply a global filter simply pass that as an argument to chronicle, or in
       your chroniclerc file.)
