I'm looking for opinions on mentioning Copr and/or EPEL and/or IUS in the pip install instructions.

Here's the PR with the actual docs changes:  https://github.com/pypa/pip/pull/3067

The goal is to give people a linux distro-friendly way (at least for fedora/centos/rhel) to upgrade pip (in distro-managed pythons) to a newer version,  i.e. something more friendly than "get-pip.py"

I started the thread in the pypa-dev list.   thought I might get broader feedback over here.

feedback in the PR is appreciated.

thanks

Marcus
