-This program is designed to generate a 12- or 24-word mnemonic using system
-entropy on an offline, post-5.4-kernel Linux system. For testing purposes, the
-command may be run in an insecure environment using `SHOOT_SELF_IN_FOOT=1`. The

-supports seed sizes of 128 bits or 256 bits, for 12 and 24 word mnemonics.
