How AI describes clang-format

Clang-Format is a formatting tool in the Clang/LLVM project that automatically formats source code according to configurable style options, with built-in styles (LLVM, Google, Chromium, Mozilla, WebKit, Microsoft) or custom styles. Styles can be supplied via -style on the command line or via a .clang-format (or _clang-format) file, which is searched in the closest parent directory and uses YAML with per-language sections. It can be used from the command line or programmatically via clang::format APIs, and supports features like disabling formatting for code ranges with special comments and using a FormatStyle structure.
