What's this?

use_markup(content) public

If there is a markup: parser_name comment at the front of the file, use it to determine the parser. For example:

# markup: rdoc
# Class comment can go here

class C
end

The comment should appear as the first line of the content.

If the content contains a shebang or editor modeline the comment may appear on the second or third line.

Any comment style may be used to hide the markup comment.
