defining projections

[Ben Lewis]

Mapserver users,
First I want to say I am really impressed with MapServer. It seems to be 
very fast and robust. I got the demo version of mapserver running on NT, and 
I've been able to set up a site pointing at other data in the UTM 
projection, but am having trouble getting data in Polyconic space to 
display.  There is no error message, just does not show up. What is the 
syntax for referring to data in:

Polyconic projection
elipsoid GRS80
Long of origin -77:45:00
Lat of origin  40:55:30
Units meters
Extent is minx, miny, maxx, maxy?

Also if I go with geographic how to I specify extent?  Does PROJ4 handle 
degrees?

Am I in effect asking about PROJ4 commands here?  Would this kind of 
information be in the PROJ4 documentation?
