That looks kinda cool, that it's mountable as a Redcarpet renderer

One feature I would love to see in RubyGems is man pages for gems, because man pages are underused and I can't go and look Github documentation up quickly as I have to break out of my dev box and go and open Chrome and look it up there

I would still use https://github.com/rtomayko/ronn, simply for the pretty HTML pages though

Ronn's HTML output is indeed pretty, but I cannot say the same of its input. In particular, I find md2man's syntax for tagged paragraphs (all lines indented by +2 spaces except the first line) to be less intrusive and easier to maintain than Ronn's (list items that begin with boldface and end with a colon, followed by +2 space indented lines).

For gem man pages I recommend checking out http://defunkt.io/gem-man/

One drawback is that it doesn't follow the standard $MANPATH directory structure (man/manX/Y.X where X is the section number and Y is the manual page) but instead uses a single flattened directory (man/Y.X).

I filed an issue about this here: https://github.com/defunkt/gem-man/issues/8
