// Most of UNSIGNED5 is in the header file.
// Let's put a few debug functions out-of-line here.

// For the record, UNSIGNED5 was defined around 2001 and was first
// published in the initial Pack200 spec.  See:
// https://docs.oracle.com/en/java/javase/11/docs/specs/pack-spec.html
// in Section 6.1, "Encoding of Small Whole Numbers".
