But when these two are controlled, all other variables are unused, except for __CL_ARGV0 that you shouldn't care about and TMPDIR (or TEMP, on Windows) that should be left in the user's control — if it's bogus, a lot more things than ASDF will break; and if the user wants to divert it, he probably knows what he's doing.
