README.md

To build Dart for Mac and Linux, we pull Fuchsia's buildtools, which is also used by Flutter. Fuchsia's buildtools includes gn, and the clang toolchain. Fuchsia buildtools vends clang-format as part of the clang toolchain. Since Fuchsia's buildtools doesn't vend a clang toolchain for Windows, we can't get a Windows clang-format binary from it. Therefore, from Chromium's buildtools here:

https://chromium.googlesource.com/chromium/buildtools

we copy the hash file for its Windows clang-format binary, and pull it down from google storage in the update.py script in this directory.

To update to a newer Windows clang-format binary, simply overwrite the hash in clang-format.exe.sha1 with a newer one, and then do a 'gclient sync'.
