the only part of the above i once read that initially confused me
was "or set on the command line" since one could interpret the
following:
$ VAR=value make ...
as setting VAR on the command line, but i'm assuming that in the
context of make, setting "on the command line" *specifically* means:
$ make VAR=value ...
correct?
