/etc/magic entries for compress(1) & pack(1)

[Chris Lent]

# 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
