Git workflow: The git-clang-format script can format lines changed in commits or staged changes.
Patch workflow: The clang-format-diff.py script reads unified diff output and reformats the changed lines.
Selective formatting: The command-line tool can format specified line or byte ranges in a single input file.
Ignore rules: A .clang-format-ignore file can contain path patterns for files that clang-format should skip.
Windows availability: The Clang build guide documents building Clang on Windows using Visual Studio.
Linux and macOS availability: The Clang guide describes building on Unix-like systems and says Clang is provided by major BSD and GNU/Linux distributions and is the default compiler for Mac OS X from Xcode 4.2.
License: The LLVM Project states that its code is licensed under the Apache 2.0 License with LLVM exceptions.
