libtest-hexstring-perl 0.03-1 (ppc64el binary) in ubuntu disco

 Test::HexString provides a single function, is_hexstr(), which asserts that
 the given string matches what was expected. When the strings match (i.e.
 compare equal using the eq operator), the behaviour is identical to the usual
 is() function provided by Test::More.
 .
 When the strings are different, a hex dump is produced as diagnostic, rather
 than the string values being printed raw.
