Update: it was difficult to figure out what parts of
https://trac.osgeo.org/proj/ were website-ish as opposed to wiki
pages, so I initially transferred the trac wiki pages [1] to GitHub
wiki [2] verbatim.  If there is further interest in making an actual
website presence for proj.4, I'm happy to move this along.
