        !            15: DESCRIPTION
        !            16:      FUnZip acts as a filter; that is,  it  assumes  that  a  ZIP
        !            17:      archive  is being piped into standard input, and it extracts
        !            18:      the first member from the archive to stdout.  Given the lim-
        !            19:      itation  on  single-member extraction, FUnZip is most useful
        !            20:      in conjunction with a secondary  archiver  program  such  as
        !            21:      tar(1).   The  following  section includes an example illus-
        !            22:      trating this usage in the case of disk backups to tape.

        !            24: EXAMPLES
        !            25:      To use FUnZip to  extract  the  first  member  file  of  the
        !            26:      archive test.zip and to pipe it into more(1):
        !            27: 
        !            28:           funzip < test.zip | more
        !            29: 
        !            30:      To use FUnZip to test the first member file of test.zip (any
        !            31:      errors will be reported on standard error):
        !            32: 
        !            33:           funzip < test.zip > /dev/null
        !            34: 
        !            35:      To use Zip and FUnZip in place of  compress(1)  and  zcat(1)
        !            36:      for tape backups:
        !            37: 
        !            38:           tar cf - . | zip -7 | dd of=/dev/nrst0 obs=8k
        !            39: 
        !            40:           dd if=/dev/nrst0 ibs=8k | funzip | tar xf -
        !            41: 
        !            42:      (where, for example, nrst0 is a SCSI tape drive).
        !            43: 
        !            44: LIMITATIONS
        !            45:      There is presently no way to  extract  any  member  but  the
        !            46:      first  from a ZIP archive.  This would be useful in the case
        !            47:      where a ZIP archive is included within another archive.
        !            48: 
        !            49:      An alternate mechanism for passing the  password  to  FUnZip
        !            50:      would be preferable to putting it on the command line.
        !            51: 
        !            52:      FUnZip would be useful under OS/2, too.
        !            53: 
        !            54:      The functionality of FUnZip  should  be  included  in  UnZip
        !            55:      directly (future release).
