- # sereal: file(1) magic the Sereal binary serialization format
- #
- # From: Ævar Arnfjörð Bjarmason <avarab@gmail.com>
- #
- # See the specification of the format at
- # https://github.com/Sereal/Sereal/blob/master/sereal_spec.pod#document-header-format
- #
- # I'd have liked to do the byte&0xF0 matching against 0, 1, 2 ... by
- # doing (byte&0xF0)>>4 here, but unfortunately that's not
- # supported. So when we print out a message about an unknown format
- # we'll print out e.g. 0x30 instead of the more human-readable
- # 0x30>>4.
- #
- # See https://github.com/Sereal/Sereal/commit/35372ae01d in the
- # Sereal.git repository for test Sereal data.
