+dart mv
+==========
+
+[![Build Status](https://drone.io/github.com/julien/dart_mv/status.png)](https://drone.io/github.com/julien/dart_mv/latest)
+
+[Dart](http://www.dartlang.org) Model/View implementation.
+
+A minimalist library that implements a Model and a View class.
+
+A basic example is provided in the "web" directory.
+
+Although the build status is "failing" since about two months,
+the tests pass in Dartium.
+
+**TODO**
+- Add more tests.
+- Generate documentation.
