  COMMAND NOTES:

  When joining with a master share, the master share must be listed first.
  The remaining shares may be listed in any order.

  The --id-str option is required only for master share joins.  For ordinary
  joins it will be ignored.

  For usage examples, see the help screen for the 'mmgen-seedsplit' command.

  PASSPHRASE NOTE:

  For passphrases all combinations of whitespace are equal, and leading and
  trailing space are ignored.  This permits reading passphrase or brainwallet
  data from a multi-line file with free spacing and indentation.
