-=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.
-

-
-=head1 BUGS
-
-To file bug reports or feature requests (other than topics listed in the
-Caveats section above) please send email to:
-
- support@daringfireball.net
-
-Please include with your report: (1) the example input; (2) the output
-you expected; (3) the output Markdown actually produced.
