 The Stateless OpenPGP CLIknown as SOP, is an RFC specification that aims to
 provide a minimal API for any implementation of the OpenPGP protocol, in
 the form of a command-line Interface. SOP can be used to test
 interoperability between different implementations of OpenPGP; the
 OpenPGP interoperability Test Suite (https://tests.sequoia-pgp.org/)
 reports results using several SOP implementations. For more information,
 please refer to the specification (https://tools.ietf.org/html/draft-dkg-
 openpgp-stateless-cli-01).
