# This script converts an SVG image to two files that can be processed
# with latex into high quality DVI/PostScript. It requires Inkscape.
# Usage:
# python svg2pstex.py [--unstable] [inkscape_command] inputfile.svg outputfile.eps_tex
# This command generates
# 1. outputfile.eps -- the converted EPS file (text from SVG stripped)
# 2. outputfile.eps_tex -- a TeX file that can be included in your
# LaTeX document using '\input{outputfile.eps_text}'
# use --unstable for inkscape < 1.0
#
# Note:
# Do not use this command as
# python svg2pstex.py [inkscape_command] inputfile.svg outputfile.pdf
# the real EPS file would be overwritten by a TeX file named outputfile.eps.
#
# This script converts an SVG image to something that latex can process
# into high quality PostScript.
