+# 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 ${base}.fig ${base}.pstex
+# python svg2pstex.py [--unstable] [inkscape_command] inputfile.svg outputfile.eps_tex
# This command generates
-# ${base}.eps the converted eps file
-# ${base}.pstex a tex file that can be included in your latex document
-# using '\input{${output}}'.
+# 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 file.fig file.eps
-# the real eps file will be overwritten by a tex file named file.eps.
+# python svg2pstex.py [inkscape_command] inputfile.svg outputfile.pdf
+# the real EPS file would be overwritten by a TeX file named outputfile.eps.
