 Blueprint Build System
 ======================
+[![Build Status](https://travis-ci.org/google/blueprint.svg?branch=master)](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
-(http://martine.github.io/ninja/) 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

+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
