>>> import pip
>>> pip.main(['install', 'boltons'])
Requirement already satisfied (use --upgrade to upgrade): boltons in ./anaconda/lib/python3.5/site-packages

This is easy, short, and uses existing syntax and an existing module.  Yes, I know technically the API isn't promised; I wouldn't object to making that API official.  But PLEASE, no new syntax for doing this!

Btw. On failure:

>>> pip.main(['install', 'nonesuch'])
Collecting nonesuch
  Could not find a version that satisfies the requirement nonesuch (from versions: )
No matching distribution found for nonesuch

At which point you may as well just (insert disclaimer about "using
pip's internal API isn't supported" here, and glossing over the fact
that pip doesn't yet have an install function with this API) do

import pip
import attr

Please forgive me for my ignorance, but it doesn't work as written - what's the actual method?
