+Secret-Sharing for Mnemonic Codes.  This SLIP describes a standard and
+interoperable implementation of Shamir's secret sharing (SSS).  SSS splits a
+secret into unique parts which can be distributed among participants, and
+requires a specified minimum number of parts to be supplied in order to
+reconstruct the original secret.  Knowledge of fewer than the required number
+of parts does not leak information about the secret.")
