    4 # sereal: file(1) magic the Sereal binary serialization format

    8 # See the specification of the format at
    9 # https://github.com/Sereal/Sereal/blob/master/sereal_spec.pod#document-header-format
   10 #
   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
   15 # 0x30>>4.
   16 #
   17 # See https://github.com/Sereal/Sereal/commit/35372ae01d in the
   18 # Sereal.git repository for test Sereal data.
