We are developing a product called MacGrass that is based on Grass as a 
powerful engine and MacGrass as an elegant front end while also adding 
capabilities, features and ease of use.

I am working on the Projection GUI and I was wondering if there is way 
to find out what projections and Ellipsoids require which parameters. It 
was not immediately apparent by looking at documentation or the source 
code in src/libes/proj or by grep'ing elsewhere.

    See <http://OpenOSX.com/MacGrassAlpha.jpg>

Is there a way to find or generate a list that shows which parameters 
are required/supported by each of the 121 projections?

For instance Albers Equal Area use False Easting and Northing, etc. that 
say UTM does not. Another example is UTM requires a zone and so forth.

Thank you for your time,
