+"""This module implements a MATLAB-like interface to the ASTRA Toolbox.
+
+Note that all functions are called with a :class:`string` as the first
+argument, specifying the operation to perform. This un-pythonic way
+is used to make transitioning from MATLAB code to Python code easier, as
+the MATLAB interface uses the same type of method calling.
+
+After an initial ``import astra``, these functions can be accessed in the
+``astra.m`` module.
