The "... file[s]" means that it you can specify the names of input
files as arguments.
There's no inherent reason why cs2cs won't work in a script, but the
cs2cs manpage won't explain any particular scripting language; those
have their own manpages.
In any case, cs2cs isn't part of GRASS, but of PROJ:
http://trac.osgeo.org/proj/
PROJ is required by GRASS, so most of the developers (and experienced
users) have some familiarity with it, but we aren't in a position to
make changes.
