      Frontend for zlib v1.0.4 compression library (C) by:

      Really it's a big nothing ;-)
      It just calls some library function, but it helps a lot
      in manipulating raw z-compressed files from shell scripts.
      (It was originally written to decompress .ztext and .zdata sections
      of a compressed ELF object dumped by the ELF Disassembler...)

      Usage:  z [-c|-d] [-0..9] [inputfile outputfile]
      ~~~~~~
          -c     =  compress  (default)
          -d     =  decompress
          -0..9  =  set compression level, 0=store  1=fast  9=best=default

        If no filename specified then stdin/stdout will be used!

      Examples:
      ~~~~~~~~~
           z -c -7 foobar foobar.z
           z -d <foobar.z >foobar
           z -d README.z | more
           z -d .ztext | ndisasm -u - > .ztext.ASM

       Note: the .z suffix is not required, but useful.
