NAME
       unpack200 - JAR Unpacking tool

SYNOPSIS
       unpack200 [ options ] input-file JAR-file

       Options may be in any order. The last option on the command line super‐
       sedes all previously specified options.

          input-file
             Name of the input file, which can be a pack200  gzip  file  or  a
             pack200  file.  The  input  could  also  be  JAR file produced by
             pack200(1) with an effort of 0. In this case the contents of  the
             input file will be copied to the output JAR file with the Pack200
             marker.

          JAR-file
             Name of the output JAR file.

DESCRIPTION
       unpack200 is a native implementation that transforms a packed file pro‐
       duced by pack200(1) into a JAR file. Typical usage:

          % unpack200 myarchive.pack.gz myarchive.jar

       In  this  example, the myarchive.jar is produced from myarchive.pack.gz
       using the default unpack200 settings.

OPTIONS
   Standard Options
       -Hvalue --deflate-hint=value

          Sets the deflation to be true, false, or keep on all entries  within
          a  JAR  file.  The default mode is keep. If true or false, overrides
          the default behavior and sets the  deflation  mode  on  all  entries
          within the output JAR file.

   Non-Standard Options
       -r --remove-pack-file

          Removes the input packed file.

       -v --verbose

          Outputs minimal messages. Multiple specification of this option will
          output more verbose messages.

       -q --quiet

          Specifies quiet operation with no messages.

       -lfilename --log-file=filename

          Specifies a log file to output messages.

EXIT STATUS
       The following exit values are returned:

           0 if successful completion;

          >0 if an error occurred.
