GMAPs

[SaijinGohan]

I am desperately trying to comprehend this whole GMAP idea. No one tells me the same thing. I got a GMAP made. Now how do I integrate this into a server? Heres two ways I got:

loadmap mapname.gmap;

or

setmap with the textfile as the gmap.

Now also, in folder config do I set the GMAP as a level?
level levels/*.gmap
or
gmap levels/*.gmap

And finally in serveroptions,
gmap=gmapname
Do I include the .gmap extension?

Any help would be appreciated. I really want to get this all organized for me in my head.
