gun will also decompress files made by Unix compress, which uses LZW
compression. These files are automatically detected by virtue of their
magic header bytes. Since the end of Unix compress stream is marked by the
end-of-file, they cannot be concantenated. If a Unix compress stream is
encountered in an input file, it is the last stream in that file.
Like gunzip and uncompress, the file attributes of the orignal compressed
file are maintained in the final uncompressed file, to the extent that the
user permissions allow it.
On my Mac OS X PowerPC G4, gun is almost twice as fast as gunzip (version
1.2.4) is on the same file, when gun is linked with zlib 1.2.2. Also the
LZW decompression provided by gun is about twice as fast as the standard
Unix uncompress command.
