Grass - Mapgen

Could some kind person tell me (in words of one syllable) what I need to
do to get Mapgen working with Grass ? and then
instructions on how to produce a simple map.

I've 'gmake4.1' on just about every directory I can find. When I type
'mapgen4.1' in the command prompt changes to

GRASS-MAPGEN and I can use the scripts such as 'make.line'. When I try

the 'make.def' I get an error or can only create a 'map.def.par' file.

I haven't tried to compile 'proj' - don't have gcc

Are there any manuals in electronic format available from any ftp site ?

Thanks for any help,
