32 Typeset cards for a set of keeper secrets.
34 This program writes a file KEEPER.ps which will contain private keys from the
35 keeper set KEEPER, specifically the keys with the given INDICES. Elements of
36 the list are either simple integers or ranges [LOW]-[HIGH]; if LOW is
37 omitted, it means 0, and if HIGH is omitted, it means the highest possible
38 index. If no INDICES are given then all secret keys are written.
40 The public keys are found in $KEYS/keeper/KEEPER/I.pub;
41 private keys are read from KEEPER/I in the current directory.
