+"""QuTiP: The Quantum Toolbox in Python
+
+QuTiP is open-source software for simulating the dynamics of closed and open
+quantum systems. The QuTiP library depends on the excellent Numpy, Scipy, and
+Cython numerical packages. In addition, graphical output is provided by
+Matplotlib.  QuTiP aims to provide user-friendly and efficient numerical
+simulations of a wide variety of quantum mechanical problems, including those
+with Hamiltonians and/or collapse operators with arbitrary time-dependence,
+commonly found in a wide range of physics applications. QuTiP is freely
+available for use and/or modification on all common platforms. Being free of
+any licensing fees, QuTiP is ideal for exploring quantum mechanics in research
+as well as in the classroom.
