The Cube Puzzle Library does not require any specific computer platform or operating system to be present. It rather requires the following third party software to be installed:

• Python 2.x (version 2.4 or higher)
  Python homepage: www.python.org
  
  Important note: The Cube Puzzle Library will not work with 3.x versions of Python, because it is not backward-compatible to the 2.x versions.

Some classes of the Cube Puzzle Library require a visual context to be present. To use these visual features, the following software needs to be installed:

• VTK (version 5.0 or higher)
  VTK homepage: www.vtk.org
  
  Important note: VTK needs to be installed with Python wrappers enabled. When configuring the VTK software set the configuration variables VTK_WRAP_PYTHON and BUILD_SHARED_LIBS to ON to tell VTK to include the Python wrappers. If you do not find these variables, then consult the appropriate documentation on how to enable the Python wrappers.
