    export WORKON_HOME=$HOME/.virtualenvs >> ~/.profile
    export PROJECT_HOME=<YOUR PROJECT DIR> >> ~/.profile
    source /usr/local/bin/virtualenvwrapper.sh

list projects:
    workon

new project:
    mkproject <PROJECT NAME>

cd to project:
    cdproject <PROJECT NAME>

work on project:
    workon <PROJECT NAME>

deactivate project:
    deactivate

freeze dependencies:
    pip freeze > requirements.txt
