  51 .SH NAME    
  52 unpack200 \- Transforms a packed file produced by pack200(1) into a JAR file for web deployment\&.
  53 .SH SYNOPSIS    
  54 .sp     
  55 .nf     
  56 
  57 \fBunpack200\fR [ \fIoptions\fR ] input\-file \fIJAR\-file\fR
  58 .fi     
  59 .sp     
  60 .TP     
  61 \fIoptions\fR
  62 The command-line options\&. See Options\&.
  63 .TP     
  64 \fIinput-file\fR
  65 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 \f3pack200\fR(1) with an effort of \f30\fR, in which case the contents of the input file are copied to the output JAR file with the Pack200 marker\&.
  66 .TP     
  67 \fIJAR-file\fR
  68 Name of the output JAR file\&.
  69 .SH DESCRIPTION    
  70 The \f3unpack200\fR command is a native implementation that transforms a packed file produced by \f3pack200\fR\f3(1)\fR into a JAR file\&. A typical usage follows\&. In the following example, the \f3myarchive\&.jar\fR file is produced from \f3myarchive\&.pack\&.gz\fR with the default \f3unpack200\fR command settings\&.
  71 .sp     
  72 .nf     
  73 \f3unpack200 myarchive\&.pack\&.gz myarchive\&.jar\fP
  74 .fi     
  75 .nf     
  76 \f3\fP
  77 .fi     
  78 .sp     
  79 .SH OPTIONS    
  80 .TP
  81 -Hvalue --deflate-hint=\fIvalue\fR
  82 .br
  83 Sets the deflation to be \f3true\fR, \f3false\fR, or \f3keep\fR on all entries within a JAR file\&. The default mode is \f3keep\fR\&. If the value is \f3true\fR or \f3false\fR, then the \f3--deflate=hint\fR option overrides the default behavior and sets the deflation mode on all entries within the output JAR file\&.
  84 .TP
  85 -r --remove-pack-file
  86 .br
  87 Removes the input pack file\&.
  88 .TP
  89 -v --verbose
  90 .br
  91 Displays minimal messages\&. Multiple specifications of this option displays more verbose messages\&.
  92 .TP
  93 -q --quiet
  94 .br
  95 Specifies quiet operation with no messages\&.
  96 .TP
  97 -lfilename --log-file=\fIfilename\fR
  98 .br
  99 Specifies a log file where output messages are logged\&.
 100 .TP
 101 -? -h --help
 102 .br
 103 Prints help information about the \f3unpack200\fR command\&.
 104 .TP
 105 -V --version
 106 .br
 107 Prints version information about the \f3unpack200\fR command\&.
 108 .TP
 109 -J\fIoption\fR
 110 .br
 111 Passes option to the Java Virtual Machine, where \f3option\fR is one of the options described on the reference page for the Java application launcher\&. For example, \f3-J-Xms48m\fR sets the startup memory to 48 MB\&. See java(1)\&.
 112 .SH NOTES    
 113 This command should not be confused with the \f3unpack\fR command\&. They are distinctly separate products\&.
 114 .PP
 115 The Java SE API Specification provided with the JDK is the superseding authority in case of discrepancies\&.
 116 .SH EXIT\ STATUS    
 117 The following exit values are returned: 0 for successful completion, and a value that is greater than 0 when an error occurred\&.
