Seeing info when changing virtualenvs with virtualenvwrapper

I wanted to see a bit about virtualenvs when I activate them with workon from virtualenvwrapper.

I added the following to $VIRTUALENVWRAPPER_HOOK_DIR/postactivate:

# This hook is run after every virtualenv is activated.

python -V
easy_install --version
pip --version

Here’s how it looks:

$ workon pip
Python 2.7.6
setuptools 3.6
pip 6.0.dev1 from /Users/marca/dev/git-repos/pip (python 2.7)

For more information on customizing with hooks, read the docs.
