These would normally be set in e.g. ~/.profile (or ~/.bash_profile
etc; there are quite a lot of files which may be read by the shell)
then inherited by all processes.

Setting environment variables in Unix is done with e.g.:

	export LANG

I'd advise against using LC_ALL, as it overrides LC_NUMERIC. This can
cause numbers to use a comma as the decimal separator, which is
problematic when writing files (most file formats require a period).

GRASS modules only use the LC_MESSAGES category directly, but some
programs and (especially) scripts invoke external programs which may
be affected by the LC_NUMERIC or LC_ALL settings (scripts which use
awk are prone to this, although I think that we have now found them
all and forced LC_NUMERIC=C).
