In your LICENSE document, you say LGPLv3, but you list:
"License :: OSI Approved :: BSD License",
as a classifier.
Also, you have license=GPLv3 in the same area.
So, is it GPLv3, LGPLv3 or BSD licensed? I'd prefer BSD licensed as it would alleviate all legal concerns I have. In #3 it looks like you intended to change it to LGPL but didn't complete the change. I believe that LGPL is acceptable for my project, but If it is still GPL'd, there is no way I can use your software.
Each .py file should have a license in it. For some reason the installed version does not include the LICENSE file, nor author, which would prevent many commercial companies from being able to use the code.
Until you fix these issues, and roll a new release, I cannot use the software. The legal state of the code is too indeterminate to risk.
