Readthedocs support

We'd like to set up a Read the Docs instance for all Pylons Projects github-hosted projects (Pyramid, Pylons, all Pyramid add-ons, all Pylons project libriaries such as Colander and Deform). The system should have the following features:

• If we choose to run our own RTD instance, we should create a buildout for it.

• Get all docs under Pylons Project namespace

• Point out docs.pylonsproject.org to the namespace

• Should show docs for all existing tags for each package.

• Automatically publish new revision of docs when a tag is made to git

• Automatically update a dev version of the docs for each package every X minutes, or on each commit?

Update documentation procedure

• Connect to github.com, create an account if you don't have one
• Verify if the project you're looking for is already updated
• Fork the project to your own account, i.e. pyramid_beaker
• Remove _themes from docs/.gitignore
• Remove docs/_themes directory if it exists
• Do git submodule add git://github.com/Pylons/pylons_sphinx_theme.git docs/_themes
• In Makefile change the line under _themes: for cd ..; git submodule update --init; cd docs
• Test out the building process; make clean html
• Send a pull request
