The pack200 files are highly compressed files that can be directly deployed to save bandwidth and reduce download time\&. 72 .PP 73 The \f3pack200\fR command has several options to fine-tune and set the compression engine\&. The typical usage is shown in the following example, where \f3myarchive\&.pack\&.gz\fR is produced with the default \f3pack200\fR command settings: 74 .sp 75 .nf 76 \f3pack200 myarchive\&.pack\&.gz myarchive\&.jar\fP 77 .fi 78 .nf 79 \f3\fP 80 .fi 81 .sp 82 .SH OPTIONS 83 .TP 84 -r, --repack 85 .br 86 Produces a JAR file by packing and unpacking a JAR file\&.

With this option, a suitable compressor must be used, and the target system must use a corresponding decompresser\&. 105 .sp 106 .nf 107 \f3pack200 \-\-no\-gzip myarchive\&.pack myarchive\&.jar\fP 108 .fi 109 .nf 110 \f3\fP 111 .fi 112 .sp 113 114 .TP 115 -G, --strip-debug 116 .br 117 Strips debugging attributes from the output\&. These include \f3SourceFile\fR, \f3LineNumberTable\fR, \f3LocalVariableTable\fR and \f3LocalVariableTypeTable\fR\&. Removing these attributes reduces the size of both downloads and installations, but reduces the usefulness of debuggers\&. 118 .TP 119 --keep-file-order 120 .br 121 Preserve the order of files in the input file\&. This is the default behavior\&. 122 .TP 123 -O, --no-keep-file-order 124 .br 125 The packer reorders and transmits all elements\&. The packer can also remove JAR directory names to reduce the download size\&. However, certain JAR file optimizations, such as indexing, might not work correctly\&. 126 .TP 127 -S\fIvalue\fR , --segment-limit=\fIvalue\fR 128 .br 129 The value is the estimated target size \fIN\fR (in bytes) of each archive segment\&. If a single input file requires more than \fIN\fR bytes, then its own archive segment is provided\&. As a special case, a value of \f3-1\fR produces a single large segment with all input files, while a value of 0 produces one segment for each class\&. Larger archive segments result in less fragmentation and better compression, but processing them requires more memory\&. 130 131 The size of each segment is estimated by counting the size of each input file to be transmitted in the segment with the size of its name and other transmitted properties\&. 132 133 The default is -1, which means that the packer creates a single segment output file\&. In cases where extremely large output files are generated, users are strongly encouraged to use segmenting or break up the input file into smaller JARs\&. 134 135 A 10 MB JAR packed without this limit typically packs about 10 percent smaller, but the packer might require a larger Java heap (about 10 times the segment limit)\&. 136 .TP 137 -E\fIvalue\fR , --effort=\fIvalue\fR 138 .br 139 If the value is set to a single decimal digit, then the packer uses the indicated amount of effort in compressing the archive\&. Level 1 might produce somewhat larger size and faster compression speed, while level 9 takes much longer, but can produce better compression\&. The special value 0 instructs the \f3pack200\fR command to copy through the original JAR file directly with no compression\&. The JSR 200 standard requires any unpacker to understand this special case as a pass-through of the entire archive\&. 140 141 The default is 5, to invest a modest amount of time to produce reasonable compression\&. 142 .TP 143 -H\fIvalue\fR , --deflate-hint=\fIvalue\fR 144 .br 145 Overrides the default, which preserves the input information, but can cause the transmitted archive to be larger\&. The possible values are: \f3true\fR, \f3false\fR, or \f3keep\fR\&. 146 147 If the \f3value\fR is \f3true\fR or false, then the \f3packer200\fR command sets the deflation hint accordingly in the output archive and does not transmit the individual deflation hints of archive elements\&. 148 149 The \f3keep\fR value preserves deflation hints observed in the input JAR\&. This is the default\&. 150 .TP 151 -m\fIvalue\fR , --modification-time=\fIvalue\fR 152 .br 153 The possible values are \f3latest\fR and \f3keep\fR\&. 154 155 If the value is latest, then the packer attempts to determine the latest modification time, among all the available entries in the original archive, or the latest modification time of all the available entries in that segment\&. This single value is transmitted as part of the segment and applied to all the entries in each segment\&. This can marginally decrease the transmitted size of the archive at the expense of setting all installed files to a single date\&. 156 157 If the value is \f3keep\fR, then modification times observed in the input JAR are preserved\&. This is the default\&. 158 .TP 159 -P\fIfile\fR , --pass-file=\fIfile\fR 160 .br 161 Indicates that a file should be passed through bytewise with no compression\&. By repeating the option, multiple files can be specified\&. There is no pathname transformation, except that the system file separator is replaced by the JAR file separator forward slash (/)\&. The resulting file names must match exactly as strings with their occurrences in the JAR file\&. If \f3file\fR is a directory name, then all files under that directory are passed\&. 162 .TP 163 -U\fIaction\fR , --unknown-attribute=\fIaction\fR 164 .br 165 Overrides the default behavior, which means that the class file that contains the unknown attribute is passed through with the specified \f3action\fR\&. The possible values for actions are \f3error\fR, \f3strip\fR, or \f3pass\fR\&. 166 167 If the value is \f3error\fR, then the entire \f3pack200\fR command operation fails with a suitable explanation\&. 168 169 If the value is \f3strip\fR, then the attribute is dropped\&. Removing the required Java Virtual Machine (JVM) attributes can cause class loader failures\&. 170 171 If the value is \f3pass\fR, then the entire class is transmitted as though it is a resource\&. 172 .TP 173 .nf 174 -C\fIattribute-name\fR=\fIlayout\fR , --class-attribute=\fIattribute-name\fR=\fIaction\fR 175 .br 176 .fi 177 See next option\&. 178 .TP 179 .nf 180 -F\fIattribute-name\fR=\fIlayout\fR , --field-attribute=\fIattribute-name\fR=\fIaction\fR 181 .br 182 .fi 183 See next option\&. 184 .TP 185 .nf 186 -M\fIattribute-name\fR=\fIlayout\fR , --method-attribute=\fIattribute-name\fR=\fIaction\fR 187 .br 188 .fi 189 See next option\&. 190 .TP 191 .nf 192 -D\fIattribute-name\fR=\fIlayout\fR , --code-attribute=\fIattribute-name\fR=\fIaction\fR 193 .br 194 .fi 195 With the previous four options, the attribute layout can be specified for a class entity, such as \f3class-attribute\fR, \f3field-attribute\fR, \f3method-attribute\fR, and \f3code-attribute\fR\&. The \fIattribute-name\fR is the name of the attribute for which the layout or action is being defined\&. The possible values for \fIaction\fR are \f3some-layout-string\fR, \f3error\fR, \f3strip\fR, \f3pass\fR\&. 196 197 \f3some-layout-string\fR: The layout language is defined in the JSR 200 specification, for example: \f3--class-attribute=SourceFile=RUH\fR\&. 198 199 If the value is \f3error\fR, then the \f3pack200\fR operation fails with an explanation\&. 200 201 If the value is \f3strip\fR, then the attribute is removed from the output\&. Removing JVM-required attributes can cause class loader failures\&. For example, \f3--class-attribute=CompilationID=pass\fR causes the class file that contains this attribute to be passed through without further action by the packer\&. 202 203 If the value is \f3pass\fR, then the entire class is transmitted as though it is a resource\&. 204 .TP 205 -f \fIpack\&.properties\fR , --config-file=\fIpack\&.properties\fR 206 .br 207 A configuration file, containing Java properties to initialize the packer, can be specified on the command line\&. 208 .sp 209 .nf 210 \f3pack200 \-f pack\&.properties myarchive\&.pack\&.gz myarchive\&.jar\fP 211 .fi 212 .nf 213 \f3more pack\&.properties\fP 214 .fi 215 .nf 216 \f3# Generic properties for the packer\&.\fP 217 .fi 218 .nf 219 \f3modification\&.time=latest\fP 220 .fi 221 .nf 222 \f3deflate\&.hint=false\fP 223 .fi 224 .nf 225 \f3keep\&.file\&.order=false\fP 226 .fi 227 .nf 228 \f3# This option will cause the files bearing new attributes to\fP 229 .fi 230 .nf 231 \f3# be reported as an error rather than passed uncompressed\&.\fP 232 .fi 233 .nf 234 \f3unknown\&.attribute=error\fP 235 .fi 236 .nf 237 \f3# Change the segment limit to be unlimited\&.\fP 238 .fi 239 .nf 240 \f3segment\&.limit=\-1\fP 241 .fi 242 .nf 243 \f3\fP 244 .fi 245 .sp 246 247 .TP 248 -v, --verbose 249 .br 250 Outputs minimal messages\&.
