+class PyNumpyQuaternion(PythonPackage):
+    """This package creates a quaternion type in python, and further enables
+    numpy to create and manipulate arrays of quaternions. The usual algebraic
+    operations (addition and multiplication) are available, along with numerous
+    properties like norm and various types of distance measures between two
+    quaternions. There are also additional functions like "squad" and "slerp"
+    interpolation, and conversions to and from axis-angle, matrix, and
+    Euler-angle representations of rotations. The core of the code is written in
+    C for speed."""
