NAME
       unpack200 - Transforms a packed file produced by pack200(1) into a JAR file for web
       deployment.

SYNOPSIS
       unpack200 [ options ] input-file JAR-file


       options
              The command-line options. See Options.

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

       JAR-file
              Name of the output JAR file.

DESCRIPTION
       The  unpack200  command  is a native implementation that transforms a packed file produced by
       pack200(1) into a  JAR  file.  A  typical  usage  follows.  In  the  following  example,  the
       myarchive.jar  file  is  produced  from  myarchive.pack.gz with the default unpack200 command
       settings.

       unpack200 myarchive.pack.gz myarchive.jar


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 the value is true or false, then the --deflate=hint option
              overrides the default behavior and sets the deflation mode on all entries  within  the
              output JAR file.

       -r --remove-pack-file
              Removes the input pack file.

       -v --verbose
              Displays  minimal  messages.  Multiple  specifications  of  this  option displays more
              verbose messages.

       -q --quiet
              Specifies quiet operation with no messages.

       -lfilename --log-file=filename
              Specifies a log file where output messages are logged.

       -? -h --help
              Prints help information about the unpack200 command.

       -V --version
              Prints version information about the unpack200 command.

       -Joption
              Passes option to the Java  Virtual  Machine,  where  option  is  one  of  the  options
              described  on  the  reference page for the Java application launcher. For example, -J-
              Xms48m sets the startup memory to 48 MB. See java(1).

NOTES
       This command should not be confused with the unpack command.  They  are  distinctly  separate
       products.

       The  Java  SE API Specification provided with the JDK is the superseding authority in case of
       discrepancies.

EXIT STATUS
       The following exit values are returned: 0 for successful completion,  and  a  value  that  is
       greater than 0 when an error occurred.
