+Run the regression test suite using settings from settings.py.
+
+The assimp_cmd (or assimp) binary to use is specified by the first
+command line argument and defaults to ``assimp``.
+
+To build, set ``ASSIMP_BUILD_ASSIMP_TOOLS=ON`` in CMake. If generating
+configs for an IDE, make sure to build the assimp_cmd project.
+
+On Windows, use ``py run.py <path to assimp>`` to make sure the command
+line parameter is forwarded to the script.
