If you make money using this software
you must donate $20 USD to a local food bank
or the food police will get you! Think of others from time to time...
To make it a menu item in Ubuntu use the Alacarte Menu Editor and add
the command python YourPathToThisFile/face.py
make sure you have made the file execuatble by right
clicking and selecting properties then Permissions and Execute
