This is (meant to become) the official WebAssembly "language" specification.

It uses Sphinx. To install that:

pip install sphinx

To make HTML (result in _build/html):

make html

To make PDF (result in _build/latex, requires LaTeX):

make pdf

To make all:

Finally, to make all and update webassembly.github.io/spec with it:

make publish

Please make sure to only use that once a change has approval.
