[GRASS-dev] Editing the Location's description file PERMANENT/MYNAME

Hi devs!

Besides _editing_ the PERMANENT/MYNAME file manually (later, not while creating
a Location), is there a "proper" way to do so? It is used for example by the
"header" instruction in ps.map. I can't trace a single reference about it in
any of the user-manuals except for in ps.map's section about the header
instruction:
<http://grass.osgeo.org/grass64/manuals/ps.map.html#header&gt;

..
%L - Location's text description
..

And, of course, in the Programmer's manual, i.e. in
<http://grass.osgeo.org/programming7/myname_8c.html&gt;

Thanks, Nikos
