Which virtual environment am I working on?

Here is how to find out (as well as set and exit the virtual environment):

Christophers-MacBook-Pro-2:scrapestat christopherspears$ workon

scrapestat
Christophers-MacBook-Pro-2:scrapestat christopherspears$ workon scrapestat
(scrapestat)Christophers-MacBook-Pro-2:scrapestat christopherspears$ echo $VIRTUAL_ENV
/Users/christopherspears/.virtualenvs/scrapestat
(scrapestat)Christophers-MacBook-Pro-2:scrapestat christopherspears$ deactivate
Christophers-MacBook-Pro-2:scrapestat christopherspears$ echo $VIRTUAL_ENV
