[Proj] Some need for updated proj-4 manuals

[Paul B. Anderson]

Hamish,

My web site is back up! This is the second time since Dr. Keith Clarke 
invited me to move my map projection material to UCSB that their servers 
have gone down. The first time was due to a forest fire. I don't know why 
the campus lost power this time (both servers were down).

Just for the record, the map projection material is actually on two 
different servers:
http://www.csiss.org/map-projections
-and-
http://www.spatial.ucsb.edu/map-projections
(at the time of my note, this server is still down)
