Convert PDF to multiple SVGs with Inkscape and pyPdf

pdf2svgs.py

"""
Author: Vitchyr Pong

Convert a PDF to svg files. Note that this is pretty slow since it makes
subprocess calls to inkscape's PDF-to-SVG command line convert.

Requirements:
    - Inkscape (https://inkscape.org/)
    - pyPdf (http://pybrary.net/pyPdf/)
    - A '/tmp' directory. If not, you must pass in another directory.
        Use 'python pdf2svg.py -h' for more information

Example Usage:
    $ python pdf2svgs.py path/to/foo.pdf path/to/svgs new_svg_name

will result in the new files:
    path/to/svgs/new_svg_name_all_p0.svg
    path/to/svgs/new_svg_name_all_p1.svg
    etc.

This is not my code. I just forked it and prepared to use in my project. Please comment in its original author's gist to give feedback.
