Python 3.5 ImportError for pyasdf.compat.user_collections_py3

I'm getting this error for Python 3.5:

$ pip install asdf
$ python -c 'import pyasdf; pyasdf.test()'
Traceback (most recent call last):

@bernie-simon had this happen once too. I'm not sure why.

Looks like the user_collections_py3 package is completely missing from the source tarball on pypi. Strange.

[embray]

I understand now. It seems that the astropy-helpers get_package_info() utility automatically excludes packages with _py2 in the name if being run with Python 3, and vise-versa. What's worse is that it does so quietly, which I don't like.

These compat packages need to be explicitly specified in MANIFEST.in to ensure that they are included in source releases.

I'll have a new release up in a bit with the fix.

@embray - It looks like that this issue still comes up with v1.0.1:

@bsipocz That must be a problem with the conda package then because the source distribution is not missing that module.
