# [gn meta-build system](https://github.com/ndsol/subgn) [![CI Status](https://travis-ci.org/ndsol/subgn.svg?branch=master)](https://travis-ci.org/ndsol/subgn)

Actually this is "sub"gn.

subgn:gn::[subninja](https://github.com/ndsol/subninja):ninja.

> GN is a meta-build system that generates

[NinjaBuild](https://ninja-build.org/) files so that you can build

~~Chromium~~ anything you want with Ninja.

The official **gn** is

[here](https://chromium.googlesource.com/chromium/src/tools/gn/). This repo

tracks the official repo with a few minor additional features.

### So is this a fork then?

Yeah, sure. Since "official gn" lives on chromium.googlesource.com, this repo

doesn't bother to clone all git commits. The history has been squashed.

Patches are kept to an absolute minimum. No changes here should ever cause a

build to fail which works with "official gn."

# Building gn

To build `out_bootstrap/gn`, type:

```

git clone https://github.com/ndsol/subgn

subgn/build.cmd

```

### How to replicate what is here
