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 specified 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, over-
	      rides 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.

       The following exit values are returned:

       0  Successful completion.
