Of the three frameworks profiled here, Pylons (http://pylonshq.com) is the most lightweight. It is not a complete bundle like Django nor does it officially support any particular template or database layer like TurboGears. There is clean, up-to-date documentation and an active user community, but the project is the youngest of the three and also the most philosophically "hackeresque."

For this reason it tends to appeal to developers with unusual project technology stacks, whereas creators of traditional CRUD-heavy content-driven sites may be more comfortable with Django. It can also be appealing to framework-haters, who may appreciate having some components ready-to-use but can easily dispose of others that are unnecessary or insufficient.
Like Django and TurboGears (and Rails), Pylons comes with an installation script to bootstrap a new project:

Paste is a Pylons-related component that acts as a kind of meta-framework creator (http://pythonpaste.org). It provides methods to start projects (see above), deploy using WSGI (see below), and even build simple web frameworks, acting as the "glue" (get it?) between various components.
