If you search the archive of this mailing list you will notice I asked this exact question about a month or 2 ago (I think). The answer I got was it is used on PyPI.org, but I don't know how to set it with setuptools (flit will probably add support after PEP 517).

To get back to this: I’m probably doing something wrong, but I haven’t managed yet to make anything show up on PyPI.org when I use “Project-URL” in metadata. 

There’s a pyobjc-core 4.0.1b1 wheel on PyPI.org that includes two Project-URL lines in its metadata, but that doesn’t add anything to the sidebar. I’ve manually verified that the metadata is present in the wheel file (as I’m using a replacement egg_info command in my setup.py file to generate this part of the metadata).

P.S. I tried to upload to test.pypi.org, but that didn’t work due to an SSL error:

$ twine upload -r testpypi dist/pyobjc_core-4.0.1b1-cp27-cp27m-macosx_10_6_intel.whl

You can add a URL in the long_description (e.g. to https://read-the-docs.readthedocs.org/ )

I know, but that adds the URL to the project description and not the sidebar. PEP 345 appears to specify metadata that could be used for this, and warehouse seems to contain to make use of this (or at least a database model that allows for specifying more links than just the default one). 

Adding links to the sidebar would be nicer with the new design on PyPI.org, but there doesn’t seem to be a clean way to add “Project-URL” metadata as described in PEP 345 to a wheel file. I could tweak my setup.py files to add Project-URL metadata, but before I do that I’d like to confirm that (a) that metadata is actually used by warehouse and (b) there is no cleaner way to add this metadata using setuptools.
