Defined in:

Overview

Metadata pages to be served in preview, in order to present information about the Middleman application and its configuration. Analogous to Firefox/Chrome's "about:" pages.

Built using a ghetto little Rack web framework cobbled together because I didn't want to depend on Sinatra or figure out how to host Middleman inside Middleman.
