Online Documentation

The online documentation is hosted at https://readthedocs.org/ under http://stackless.readthedocs.io/. Because readthedocs supports Sphinx, the documentation updates mostly automatically. There is a single obstacle. Our documentation is to big to build a single-html page with the limited cpu-time per build. Therefore we need a configuration file ".readthedocs.yml" in the root directory to turn off additional formats:

#!yaml
# Don't build any extra formats
formats:
    - none

See http://docs.readthedocs.io/en/latest/yaml-config.html#formats for details.
