-# This script converts an SVG image to something that pdflatex can process
-# into high quality PDF.
+# 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 ${base}.svg ${base}.pdft
+# python svg2pdftex.py [--unstable] [inkscape_command] inputfile.svg outputfile.pdf_tex
# This command generates
-# ${base}.pdf the converted pdf file
-# ${base}.pdft a tex file that can be included in your latex document
-# using '\input{${base}.pdft}'
+# 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 file.svg file.pdf
-# the real pdf file will be overwritten by a tex file named file.pdf.
+# python svg2pdftex.py [inkscape_command] inputfile.svg outputfile.pdf
+# the real PDF file would be overwritten by a TeX file named outputfile.pdf.
