Unknown distribution option: 'long_description_content_type'

[Sergey Vilgelm]

Hi, I would like to use description-content-type
Since version 4.0.0 this parameter should be available, but I see warning:

    (marshmallow-objects-kvxIyAxI) bash-3.2$ python setup.py --version
    /Users/svilgelm/Library/Mobile Documents/com~apple~CloudDocs/projects/marshmallow-objects/.eggs/pbr-4.0.1-py2.7.egg/pbr/core.py:120: UserWarning: Unknown distribution option: 'long_description_content_type'
      warnings.warn(msg)
    1.0.11

Here is setup.py and setup.cfg files:

    (marshmallow-objects-kvxIyAxI) bash-3.2$ cat setup.py
    #!/usr/bin/env python

    import setuptools

    setuptools.setup(setup_requires=['pbr>=4.0.1'], pbr=True)

I noticed this too, and on further investigation I believe that it's not really solvable by PBR as things currently stand with setuptools. I've filed [1] which would allow it to be set

It's blocked waiting for setuptools maintainers to approve the pull request linked from comment #1 and then tag a release.

[Sergey Vilgelm (sergey.vilgelm)]

The pull was merged on May 18, and included in release #39.2.0 on Mya 19. Since that time @Ian Wienand didn't work on the commit, so I decided to continue his work.
