7# See the specification of the format at

10# I'd have liked to do the byte&0xF0 matching against 0, 1, 2 ... by
11# doing (byte&0xF0)>>4 here, but unfortunately that's not
12# supported. So when we print out a message about an unknown format
13# we'll print out e.g. 0x30 instead of the more human-readable
14# 0x30>>4.

16# See https://github.com/Sereal/Sereal/commit/35372ae01d in the
17# Sereal.git repository for test Sereal data.
