# Formats for various forms of compressed data
# Formats for "compress" proper have been moved into "compress.c",
# because it tries to uncompress it to figure out what's inside.
# According to gzip.h, this is the correct byte order for packed data.
#
0 string \037\036 packed data
#
# This magic number is byte-order-independent.
#
0 short 017437 old packed data
#
# XXX - why *two* entries for "compacted data", one of which is
# byte-order independent, and one of which is byte-order dependent?
#
0 short 0x1fff compacted data
0 string \377\037 compacted data
0 short 0145405 huf output

# Squeeze and Crunch...
# These numbers were gleaned from the Unix versions of the programs to
# handle these formats. Note that I can only uncrunch, not crunch, and
# I didn't have a crunched file handy, so the crunch number is untested.
