In general, we add packages one commit at a time, so we prefer to
receive this as two patches. First, a patch that adds python-sane, and
then a second patch adding ocrfeeder.

Overall LGTM, thanks!

I would write, simply, "Complete OCR Suite". For some reason, the linter
doesn't complain for me, but it should recommend against starting
synopses with an article. That is, with "a", "an", or "the".

And make sure to end the sentence with a period "."

Great!

We prefer to use complete sentences in the description. You can always
make it simple:

"This package provides Python interface to the SANE scanner and frame
grabber interface for Linux."

I looked in the repo and it doesn't look like the expat license:

I'm not sure what it is? Can you do a little research? That FSF license
directory might help.
