bozohttpd mime types etting for markdown files

[Mayuresh <mayuresh%acm.org@localhost>]

The man page says:
     -M suffix type encoding encoding11
                Adds a new entry to the table that converts file suffixes to
                content type and encoding.  This option takes four additional
                arguments containing the file prefix, its “Content-Type”,
                “Content-Encoding”, and “Content-Encoding” for HTTP/1.1
                connections, respectively.  If any of these are a single dash
                (“-”), the empty string is used instead.

Tried '-M md text/markdown - -' and variations like .md instead of md,
utf-8 instead of - etc.

What is a proper way to specify this?
