Something like that, similar to forthcoming R `rc' files (now profile):

	system rc from R_HOME/VERSION/...
	site rc from R_HOME/site/.../Rrc
	user rc from ./.Rrc or ~/.Rrc

	system environ from R_HOME/VERSION/...
	site environ from R_HOME/site/.../Renviron
	user environ from ./.Renviron or ~/.Renviron

Of course, then we'd need options

	--no-user-env
	--no-site-env

and I think I'd maybe want (for 1.0)

	--no-user-file => --no-user-rc
	--no-site-file => --no-site-rc

or (maybe better) keep what we have and interpret it as `files' so that
neither rc no env file would be used.

-k

Btw, I'd use `-r' ...
