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."""
