34 | The private keys are stored in KEEPER/I for each 0 <= I < N in the current | |
35 | directory; presumably you'll do something sensible with them. A new | |
36 | directory $KEYS/keeper/KEEPER is created (it is an error if it already | |
37 | exists), containing the public keys I.pub and some metadata meta. | |
