SVG scrubber and optimizer (Python 3 module)

 Scour is a Python module that aggressively cleans SVG files, removing a lot of
 unnecessary information that certain tools or authors embed into their
 documents. The goal of scour is to provide an identically rendered image
 (i.e. a scoured document should have no discernible visible differences from
 the original file) while minimizing the file size.
 .
 WARNING: Scour is intended to be run on files that have been edited in Vector
 Graphics editors such as Inkscape or Adobe Illustrator. Scour attempts to
 optimize the file, and as result, it will change the file's structure and
 (possibly) its semantics. If you have hand-edited your SVG files, you will
 probably not be happy with the output of Scour.
 .
 Never use scour to overwrite your original file!
