Comment 3 for bug 1453370

After putting out the 4.12.0 release I updated the documentation to include the intersphinx targets. I tested it out with a test document that looks like this:

Intersphinx test documentation for Beautiful Soup
=================================================

* A class: :py:class:`bs4.BeautifulSoup`
* Another class: :py:class:`bs4.Tag`
* An attribute: :py:attr:`bs4.Tag.name`

In conf.py for the test project, my intersphinx_mapping looks like this:

intersphinx_mapping = {
    "beautifulsoup4": (
        "https://www.crummy.com/software/BeautifulSoup/bs4/doc/", None
    )
}
