Can't seem to get to either Baylor or ITC right now to check, but it's 
there in the 'grass5' man page:

ENVIRONMENT VARIABLES
    User Interface Environment Variable
        The  grass5  program  will  check  for the existence of an
        environment variable called GRASS_GUI which indicates  the
        type  of user interface for GRASS to use. If this variable
        is not set when grass5 is run, then it will be created and
        then  saved  in the $HOME/.grassrc5 file for the next time
        GRASS is run.

        There is an order of precedence in the way  grass5  deter-
        mines  the  user   interface  to use. The following is the
        hierarchy from highest precedence to lowest.

        The  user  may  add   own  environment  variable  settings to
        $HOME/.grassrc5 file which are used during next startup of
        GRASS (list of implemented environment variables).

etc.

It's basically calling everything 'environment variables'.  Confusing.  
I guess Markus needs to work on this one next, after he takes care of 
html/env_vars.html.

Ah.
