I'd like to make both these spots include a link to setting up virtual environments.

Two ``virtualenv`` related questions before working on that:

+ Is there any reason **not** to point people straight at ``virtualenvwrapper`` instead of ``virtualenv``?
+ Any virtue to mentioning the ``conda`` approach? I'd lean against it on the philosophy that new users want instructions more than options, and it invites questions about a second tool when ``virtualenv`` seems to already get the job done.
