NAME
       unpack200 - JAR Unpacking tool

SYNOPSIS
       unpack200 [ OPTIONS ] input-file JAR-file

PARAMETERS
       The options may be in any order. The last option on the command line supersedes all previously speci-fied specified
       fied options.  For a discussion of the options, see OPTIONS below.

       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
       The unpack200 tool is a native implementation that transforms a packed file  produced  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
       -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  mes-sages. messages.
              sages.

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

       -lfilename --log-file=filename
              Specifies a log file to output messages.

       The following exit values are returned:

       0  Successful completion.

       >0  An error occurred.
