WIP for ninja.

* Fails to build, the python bootstrap tools seems to be generating
some build rules twice.
 * Not enough experience with Python to solve this, so leaving the
package as broken.

+DESCRIPTION="
+	Ninja is a small build system with a focus on speed. It differs from other
+	build systems in two major respects: it is designed to have its input files
+	generated by a higher-level build system, and it is designed to run builds
+	as fast as possible.
+
+	Why yet another build system?
+	Where other build systems are high-level languages Ninja aims to be an
+	assembler.
+
+	Ninja build files are human-readable but not especially convenient to write
+	by hand. (See the generated build file used to build Ninja itself.) These
+	constrained build files allow Ninja to evaluate incremental builds quickly.
+	For the Chrome browser on Linux (the motivating project behind Ninja),
+	Ninja is under a second for a no-op build where the equivalent Makefiles
+	took over ten seconds.
+
+	Ninja's low-level approach makes it perfect for embedding into more
+	featureful build systems. Via gyp it can build Chrome and v8 and node.js
+	etc.; via CMake it can build LLVM and KDE and Blender etc.
