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