Neither of these two flags have any effect when used on a project that includes

A reasonable use of the `--python-tag` argument would be for a project that
uses Python syntax only introduced in a particular Python version. There are
no current examples of this, but if wheels had been available when Python 2.5
was released (the first version containing the `with` statement), wheels for a
project that used the `with` statement would typically use `--python-tag py25`.
+However, unless a separate version of the wheel was shipped which avoided the

Typically, projects would not specify Python tags on the command line, but
would use `setup.cfg` to set them as a project default::
