Introduction
------------
``virtualenv`` is a tool to create isolated Python environments.
The basic problem being addressed is one of dependencies and versions,
and indirectly permissions. Imagine you have an application that
needs version 1 of LibFoo, but another application requires version
2. How can you use both these applications? If you install
everything into ``/usr/lib/python2.7/site-packages`` (or whatever your
platform's standard location is), it's easy to end up in a situation
where you unintentionally upgrade an application that shouldn't be
upgraded.
Or more generally, what if you want to install an application *and
leave it be*? If an application works, any change in its libraries or
the versions of those libraries can break the application.
Also, what if you can't install packages into the global
``site-packages`` directory? For instance, on a shared host.
In all these cases, ``virtualenv`` can help you. It creates an
environment that has its own installation directories, that doesn't
share libraries with other virtualenv environments (and optionally
doesn't access the globally installed libraries either).
