#!/usr/bin/perl
# genspic2gnuplot - Copyright 2004 Ian Jackson - see below
#
# Reads a `genspic' file on stdin. Takes exactly one arg, <pfx>.
#
# Produces various output files:
# <pfx>.gnuplots.sh run this to display results
# <pfx>,<Kind><N>.gnuplot-cmd gnuplot script for displaying:
# <pfx>,<Kind><N>-<M>.gnuplot-data gnuplot-format input data
# <pfx>,gnuplot-fifo working fifo for .gnuplots.sh
# where
# <Kind> is Freq or Time (according to the type of analysis)
# <N> is the count, starting at 0, of which report this is from gnucap
# <M> is the individual column of Y data
#
# Limitations
#
# There's no easy way to mess with the gnuplot settings.
#
# This whole scheme is very clumsy. There should be a driver program
# with command-line option parsing.
