Check for stylistic and formal issues in .rst and .py files included in the documentation.
copied from cf-staging / sphinx-lintSphinx Lint is based on rstlint.py from CPython. It should be reasonably fast so it's comfortable to use as a linter in your editor, be usable on a single file, not give any false positives (probably a utopia, but let's try), not spend too much effort finding errors that sphinx-build already finds (or can easily find), and focus on finding errors that are not visible to sphinx-build.
