The intention right now is for those project pages to document proj4 projection methods as they are implemented. The intention is when a new projection method is added to Proj4, such as when +proj=times was just added this past release, a new page will be added there with all relevant information, math, and pointers.

Something like http://proj4.org/projections/sinu.html There is a ton of material in the PostScript files (I do wish we had the original latex so there wasn't risk to getting the math notation wrong) that needs to be brought into these "projection pages", but we now have some scaffolding to support people contributing to this effort.
