A project directory is associated with a virtualenv, but usually contains the source code under active development rather than the installed components needed to support the development. For example, the project directory may contain the source code checked out from a version control system, temporary artifacts created by testing, experimental files not committed to version control, etc.
A project directory is created and bound to a virtualenv when mkproject is run instead of mkvirtualenv. To bind an existing project directory to a virtualenv, use setvirtualenvproject.
A new project directory can be created empty, or populated using one or more template plugins. Templates should be specified as arguments to mkproject. Multiple values can be provided to apply more than one template. For example, to check out a Mercurial repository from on a project on bitbucket and create a new Django site, combine the bitbucket and django templates.
$ mkproject -t bitbucket -t django my_site
