-
-=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/
-
-

-
-
-=item B<--html4tags>
