# ngspice2genspic - Copyright 2004 Ian Jackson - see below
#
# Reads the output from ngspice and outputs a `genspic' file
# for use with genspic2gnuplot. Takes no arguments or options.
#
# Limitations
#
# Only frequency (.AC) and transient plots have been tested.
#
# Displaying voltages and currents on the same .TRAN graph won't work
# well because they currently have to have the same Y scale.
#
# This whole scheme is very clumsy. There should be a driver program
# with command-line option parsing.
