# Hi,
# Here's the necessary lines to ADD to /etc/magic
# to allow file(1) to recognize files produced by compress(1) and pack(1).
# This has been tested on System V Releases 2.0 and 3.0 (3B5 and 3B2,
# respectively.) Note that the file will also tell how many bits
# the code lengths are for compressed files.
#
# To test:
# $ # extract the archive
# $ sh magic.shar
# $ shar: extracting 'compress.magic' (388 characters)
# $ cp compress.magic /tmp/x
# $ compress /tmp/x
# $ # Test file(1) with compress.magic instead of /etc/magic
# $ file -m compress.magic /tmp/x.Z
# /tmp/x.Z: compressed data - with 16 bits
# $ rm -f /tmp/x.Z
#
# Enjoy,
# Chris Lent
