Really cool stuff!

The only thing I=92d change is the header "Scripting examples=94. It = should be =93Gschem Scripting Examples=94. The gschem and gnetlist Guile = API=92s are very different, so it could confuse = readers.


Currently the language = confuse me. I wrote a lot of helper scripts during my Cadence days. = SKILL is also a kind of LISP, but it strikes me how different the = notation is. Where SKILL hardly used any other magic characters but ', = guile seems to use *,? and ! in ways I am not able to grok by just = looking at the = code.

I would be happy if the = scripts were elaborated a bit more regarding 'how to think when = programming guile in geda' for people who has programmed before, but not = in guile.

I just got started with John's = example for back-end programming in gnetlist, and I really think that = gnet-devel.scm should be a part of the distribution. =

=93gnetlist -i=94 now gives you all of = the gnet-devel functionality (thanks, Peter B.), so that would be = redundant.

Playing around on the REPL command line reminds me of the = CIW window in Cadence. Does the same exist for gschem too?
