+=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 and 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.:

+
+=item B<-v>, B<--version>
