You are looking at a page about doing
You can do anything in cow by using the do command.
Do lets you do things that have no explicit command.. maybe you feel like floating 2 inches of the ground.. so:
do floats 2 inches above the ground
Anything you do is prefaced with your name so if you are called boris, this would be seen as:
Boris floats 2 inches above the ground
If someone were to create a command called float, then you would merely type float and the command would do the typing for you.
