"""
A txt2tags entry formatter for pyblosxom.

Txt2tags (http://txt2tags.org) is a document generator. It reads a text file
with minimal markup such as **bold** and //italic// and converts it to the
following formats: HTML, XHTML, SGML, DocBook, LaTeX, Lout, Man page, Creole,
Wikipedia / MediaWiki, Google Code Wiki, PmWiki, DokuWiki, MoinMoin,
MagicPoint, PageMaker, AsciiDoc, ASCII Art and Plain text.

Install txt2tags and copy this file to your pyblosxom plugins directory. Entry
files with a .t2t extension will be parsed by this plugin.

You can configure this as your default preformatter for .txt files by
configuring it in your config file as follows::

    py['parser'] = 'txt2tags'

or in your blosxom .txt file entries, place a '#parser txt2tags' line after the
title of your blog::

    My Little Blog Entry
    #parser txt2tags
    My main story...

Further configuration options (default values set as follow):

    # Document encoding
    py['t2t_encoding'] = 'iso-8859-1'

    # Insert CSS-friendly tags
    py['t2t_css-sugar'] = 0

    # Show a table of contents
    py['t2t_toc'] = 0

    # Hide email adressess in HTML body
    py['t2t_mask-email'] = 0

    # Enumerate titles
    py['t2t_enum-title'] = 0
