=head1 NAME
B<Markdown>
=head1 SYNOPSIS
B<Markdown.pl> [ B<--html4tags> ] [ B<--version> ] [ B<-shortversion> ]
[ I<file> ... ]
=head1 DESCRIPTION
Markdown is a text-to-HTML filter; it translates an easy-to-read /
easy-to-write structured text format into HTML. Markdown's text format
is most similar to that of plain text email, and supports features such
as headers, *emphasis*, code blocks, blockquotes, and links.
Markdown's syntax is designed not as a generic markup language, but
specifically to serve as a front-end to (X)HTML. You can use span-level
HTML tags anywhere in a Markdown document, and you can use block level
HTML tags (like <div> and <table> as well).
For more information about Markdown's syntax, see:
http://daringfireball.net/projects/markdown/
=head1 OPTIONS
Use "--" to end switch parsing. For example, to open a file named "-z", use:
Markdown.pl -- -z
=over 4
=item B<--html4tags>
Use HTML 4 style for empty element tags, e.g.:
<br>
instead of Markdown's default XHTML style tags, e.g.:
<br />
=item B<-v>, B<--version>
Display Markdown's version number and copyright information.
=item B<-s>, B<--shortversion>
Display the short-form version number.
