pip2 not present on Debian

[zachriggle]

On Debian 7.X, there is no pip2 command.

$ apt-get install python-pip
$ pip2
-bash: pip2: command not found

On the latest Ubuntu LTS (14.04), /usr/bin/pip resolves to the python2.7 version even though the default version of Python is Python3.

Everywhere I've look, pip always points to the Python 2.7 pip (if installed). However, pip2 does not always exist. Is there a reason we use/recommend pip2?

Debian appears to use the pip-2.7 naming scheme, which differs from Ubuntu's pip2 (which I imagine is where the original name came from).

In contrast, python2 is present on all systems that I looked at (which Python 2.7 installed).

Just wanted to point all this out and check to see if there's any objections before I change README.md.
