# IronPython example program to demonstrate Tao Framework
#
# Steps:
# 1. Install Tao Framework.
# 2. Create an empty IronPython project in Visual Studio
# 3. Place Tao.OpenGl.dll and Tao.FreeGlut.dll in directory of Python source file.
#    These DLL files are found in C:\Program Files (x86)\TaoFramework\bin
# 4. Place freeglut.dll in directory of Python source file.
#    This DLL file is found in C:\Program Files (x86)\TaoFramework\lib
# 5. Paste this source code into the Python source file
# 6. Run. You should see a grey teapot.
