Auto-rename OS X terminal tab with virtualenv name

I often work on multiple Python projects at a time, each with its own virtual environment and terminal tab. I use virtualenvwrapper to manage my virtualenvs.

I like to have each terminal tab named after the project loaded in it, so I changed my preactivate script to look like this:

#!/bin/bash
# This hook is run after every virtualenv is activated.
# The environment name is passed as argument

# renames the current os x terminal tab title
printf "\e]1;$1\a"

Now, whenever I switch to a virtualenv with the workon command, my tab is automatically updated.

I added a similar command to the predeactivate command to remove the terminal tab name:

#!/bin/bash
# This hook is run before every virtualenv is deactivated.

# remove virtualenv name from terminal tab name
printf "\e]1;\a"

This works with iTerm2 as well.
