There is a 'python-web' module as well, would that be a good fit for
this package?  python.scm had to be split up since it was causing
problems for the Guile compiler.

If Python 3 is unsupported, please add a comment about it.  Otherwise
it's better to add a Python 3 variant and make the Py2 variant inherit
from it.

Synopses should not start with an article (I believe `guix lint` will
warn about this).  Simply "High-level cross-protocol URL grabber".

Please turn this into one or more complete sentences.
E.g. "@code{urlgrabber} is a Python library that unifies access to
...  It supports bla bla.".

This should be LGPL2.1+ as mentioned in the code headers.
