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.
