32Create a new set of keeper keys.
33
c47f2aba 34The key nubs are stored in KEEPER/I for each 0 <= I < N in the current

MW
35directory; presumably you'll do something sensible with them. A new
36directory $KEYS/keeper/KEEPER is created (it is an error if it already
c47f2aba 37exists), containing the key store directories and some metadata meta.
