3 * Core GN templates and configuration
4 * Core Python build scripts
6 Since this directory is DEPS'ed in by some other repositories (webrtc, pdfium,
7 v8, etc), it should be kept as self-contained as possible by not referring
8 to files outside of it. Some exceptions exist (`//testing`, select
9 `//third_party` subdirectories), but new dependencies tend to break these other
10 projects, and so should be avoided.
12 Changes to //build should be landed in the Chromium repo. They will then be
13 replicated to the stand-alone [build repo](https://chromium.googlesource.com/chromium/src/build)
14 by the [gsubtreed tool.](https://chromium.googlesource.com/infra/infra/+/master/infra/services/gsubtreed)
17 * `//build/config` - Common templates via `.gni` files.
18 * `//build/toolchain` - GN toolchain definitions.
19 * `Other .py files` - Some are used by GN/Ninja. Some by gclient hooks, some
20 are just random utilities.
22 Files referenced by `//.gn`:
23 * `//build/BUILDCONFIG.gn` - Included by all `BUILD.gn` files.
24 * `//build/secondary` - An overlay for `BUILD.gn` files. Enables adding
25 `BUILD.gn` to directories that live in sub-repositories.
26 * `//build_overrides` -
27 Refer to [//build_overrides/README.md](../build_overrides/README.md).
