libmenhir-coq 20200123-1 (arm64 binary) in ubuntu focal

 The Menhir parser generator, when invoked with the --coq option, produces
 parser code in the Coq language.
 .
 These parsers must be linked against this library, which provides
 both an interpreter (which allows running the generated parser) and
 a validator (which allows verifying, at parser construction time,
 that the generated parser is correct and complete with respect to
 the grammar).
