Comment (by Ionic):

 Hm, or well, if you write it as a subport into the same Portfile, that
 *might* work, but there's also a high chance to completely break
 everything, since it looks like sometimes we handle port names case-
 sensitively and sometimes we don't. Bad idea, I'd say.

 Oh, and likewise renaming it back to `mediainfo` is a bad idea as well,
 since in that case users didn't have `mediainfo` installed and then
 installed `MediaInfo` (most likely as a dependency) won't be able to
 "upgrade" to the `mediainfo` port.
