# Setup:
#
# 1. Create a directory to hold the virtual environments.
# (mkdir $HOME/.virtualenvs).
# 2. Add a line like "export WORKON_HOME=$HOME/.virtualenvs"
# to your .bashrc.
# 3. Add a line like "source /path/to/this/file/virtualenvwrapper.sh"
# to your .bashrc.
# 4. Run: source ~/.bashrc
# 5. Run: workon
# 6. A list of environments, empty, is printed.
# 7. Run: mkvirtualenv temp
# 8. Run: workon
# 9. This time, the "temp" environment is included.
# 10. Run: workon temp
# 11. The virtual environment is activated.
#
# Locate the global Python where virtualenvwrapper is installed.

# a new command from a shared library, but "command" will pick up

virtualenvwrapper is a set of extensions to Ian Bicking's virtualenv
tool. The extensions include wrappers for creating and deleting
virtual environments and otherwise managing your development workflow,
making it easier to work on more than one project at a time without
introducing conflicts in their dependencies.
