# Load all Spice files in a given folder and create a PNG image of each
# sub-circuit.

# Loop over spice files; read each spice file (by calling
# `zspice <options>`) and then load each sub-circuit
# into the Schem window and print it to postscript.
#
# Terminology: ZDB uses the Verilog name Module for a Spice "sub-circuit"
# and the name Primitive for a Spice "model".
