Exporting Godot Documentation

For this example, we're going to build a HTML archive of Godot's documentation at version 2.1.4.

Other versions can be looked up by checking out particular release branches or commits.

Tested on Ubuntu 21.10.

1. Get sphinx and the readthedocs theme:
   sudo apt install python3-pip
pip3 install sphinx sphinx_rtd_theme

2. Clone the docs repo:
   git clone --recursive https://github.com/godotengine/godot-docs
cd godot-docs

3. Switch to the 2.1 branch:
   git checkout --force origin/2.1

4. Generate the export:
   sh
make html
exit

An offline HTML build will then be available at _build/html/index.html.

The ReadTheDocs platform supports EPub and PDF exports also. These features however have been disabled in the Godot repo due to export filesize and error concerns. See .readthedocs.yml.
