A friend of mine said they had the perception that GNOME technologies appeared unfinished due to the nature that manpages were not installed for the APIs. While I didn't particularly agree with that sentiment, I did decide I would make manpages for them.
The gnome-manpages can be found here.
The resulting manpages look very similar to what you look at in devhelp, except in a terminal. They work with man -k keyword as well as Shift+K in VIM for typedefs, macros, functions, and structs. I do hope to provide configure patches to generate these in the various projects at some point soon.
