Currently, pip3 --user installed stuff can be updated with:
pip3 install --upgrade --user $(pip3 list --user -o | cut -f 1 --delim=' ')

But that isn't obvious/discoverable

Note that upstream considers a bulk-upgrade command to be gated on
using a proper dependency solver:

* https://github.com/pypa/pip/issues/59#issuecomment-52424510
* https://github.com/pypa/pip/issues/988

However, using a proper dependency solver is in turn gated on having
programmatic access to the relevant dependency constraints *before*
you start installing anything.

This is not *entirely* true, it’ll just be *really* slow without it since we’ll

need to download files to get their dependencies. The flip side is that

It’s pretty easy for us to add it in right now for Wheels, but of course, we

can’t for sdists, which I think is fine because it’s just another reason why

all projects should strive to upload wheels when they can :)

The lack of a proper resolver when doing bulk upgrades is also a much
bigger issue for pip/PyPI than it was for yum as the latter relied
heavily on repo curation to limit the chance of conflicts. PyPI by
contrast is a complete free-for-all where blindly upgrading everything
in --user can easily break previously working setups.

So if we wanted to offer this, it would likely need to be as a
standalone (pip installable?) script that was equivalent to the above
bash snippet.

Cheers,
Nick.
