Build the SST docs/website:
---------------------------

* install sphinx (`$ sudo apt-get install python-sphinx`)
* run `make_actions_rst.py`, which will create `actions.rst`
* move `docs/assets/nature.css_t` to
    `/sphinx/themes/nature/static/nature.css_t`
* go up to the main SST directory and run: `sphinx-build -b html docs sst_docs`

This will produce HTML documentation in the sst_docs directory. Open
`index.html` with your browser.
