Postscript?!?! (was ASM-1 homepage improvement!)

   I just added the ADSR schematic to the ASM-1 homepage.
[...]
   (building a Postscript schematic the way I do it requires many
   renderings of the Postscript, one for each try). 

Postscript?!?!  What?!?!

<checking the ASM-1 page...>  Postscript/Emacs/Ghostscript/PDF!?!?!
What a crazy way to draw a schematic!  This is very cool.  I like it.

The nice thing about this approach is the type of control you have
over the schematic -- "I want a transistor to look like *this*".  Then
later you can say, "no wait a second, it'd be better if a transistor
looked like *this*" and all the transistors are updated.  If you have
schematic objects dependent upon other objects (ie., postscript
subroutines) they get updated too.  Schematic objects can draw
dependant upon given parameters.  Positioning can be done correctly
too; "place this resistor 2.4 inches north of the collector terminal
of that transistor", that sort of thing.

I've done some PC board designs in a similiar way (but with a
Lisp-based drawing program in between; it'd probably have been a lot
easier to go directly to Postscipt).
