# This script converts an SVG image to two files that can be processed
# with pdflatex into high quality PDF. It requires Inkscape.
# Usage:
# python svg2pdftex.py [--unstable] [inkscape_command] inputfile.svg outputfile.pdf_tex
# This command generates
# 1. outputfile.pdf -- the converted PDF file (text from SVG stripped)
# 2. outputfile.pdf_tex -- a TeX file that can be included in your
# LaTeX document using '\input{outputfile.pdf_text}'
# use --unstable for inkscape < 1.0
#
# Note:
# Do not use this command as
# python svg2pdftex.py [inkscape_command] inputfile.svg outputfile.pdf
# the real PDF file would be overwritten by a TeX file named outputfile.pdf.
