1 # About
2 `//build` contains:
3  * Core GN templates and configuration
4  * Core Python build scripts
5
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.
11
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/+/main/infra/services/gsubtreed)
15 Note: You can find all directories already  available through gsubtreed in the
16 [list of all chromium repos](https://chromium.googlesource.com/).
