In bash, I believe it is possible to enable tab completion on the terminal for terms that are specific to the executable being invoked.

For example, given an executable "eat" with valid arguments {cake, carrot, banana}, typing 'eat car' should complete to 'eat carrot'.

I believe this is possible because I have seen it with 'ant' tab-completing its targets (though how this was set up I don't know).

How can this behaviour be implemented?
