+CLI (:program:`covert` command) to Wand compiler (:issue:`100`)
+   Primary interface of ImageMagick is :program:`convert` command.
+   It provides a small *parameter language*, and many answers on the Web
+   contain code using this.  The problem is that you can't simply
+   copy-and-paste these code to utilize Wand.
+
+   This feature is to make these CLI codes possible to be used with Wand.

+Supporting :meth:`__array_interface__` for NumPy
+   It makes :func:`numpy.asarray()` able to take :class:`~wand.image.Image`
+   object to deal with its pixels as matrix.

+   Its branch name will be :branch:`numpy`.
