Blueprint Build System ====================== [](https://travis-ci.org/google/blueprint) Blueprint is a meta-build system that reads in Blueprints files that describe modules that need to be built, and produces a [Ninja](https://ninja-build.org/) manifest describing the commands that need to be run and their dependencies. Where most build systems use built-in rules or a domain-specific language to describe the logic for converting module descriptions to build rules, Blueprint delegates this to per-project build logic written in Go. For large, heterogenous projects this allows the inherent complexity of the build logic to be maintained in a high-level language, while still allowing simple changes to individual modules by modifying easy to understand Blueprints files.
