The spec says:
> As you discover more phrases of power, you can re-run the program with additional -p command line options; during judging (except for the lightning division), the program will be passed all the phrases of power.
If you're competing in the lightning round, you'll have an advantage by learning more phrases of power and embedding them in your program. For the normal round, if your program is sufficiently sophisticated, you won't need to know any of the phrases of power in advance.
