The lack of documentation has been a long standing issue in the Static Analyzer, and one of the leading reasons behind this was a lack of good documentation infrastucture. This lead serious drawbacks, such as * Not having proper release notes for years * Not being able to have a sensible auto-generated checker documentations (which lead to most of them not having any) * The HTML website that has to updated manually is a chore, and has been outdated for a long while * Many design discussions are now hidden in phabricator revisions This patch implements a new documentation infrastucture using Sphinx, like most of the other subprojects in LLVM. It transformed some pages as a proof-of- concept, with many others to follow in later patches. The eventual goal is to preserve the original website's (https://clang-analyzer.llvm.org/) frontpage, but move everything else to the new format. Some other ideas, like creating a unipage for each checker (similar to how clang-tidy works now), are also being discussed. Patch by Dániel Krupp!
