#38

Reposting the issue here:

There are two more entries that could be marked green because people have ported them to python 3 as separate libraries. (This is from file overrides.json in caniusepython3.)

"python-ldap": "https://github.com/pyldap/pyldap"
"python-openid": "https://pypi.python.org/pypi/python3-openid"

python-openid is one of the last packages still marked in white. It could be marked in green as above.

google-apputils is still listed in white.

But for https://pypi.python.org/pypi/google-apputils it says "Obsolete. Please migrate to absl-py instead."

https://pypi.python.org/pypi/absl-py does support Python 3.

Perhaps google-apputils should be removed from the list, or linked to the new library.
