Oh, one more thing: Last time I used circuit_macros, you had to edit all
the *.m4 files it comes with by hand. Most of the *.m4 files it comes
with has reference to its installation path, but it's all hard-coded and
needs to be modified to reflect the correct installation path on your
system. A little whacky but I guess there's no equivalent to $0 or
argv[0] in m4. =(
BTW, m4 is nice to learn (even a little.) It'll help you not only use
circuit_macros better, but it's also used by autoconf/automake so you'll
be able to write your own subroutines and codes in autoconf/automake as
well.
