java.util.jar
Provides classes for reading and writing the JAR (Java ARchive)
file format, which is based on the standard ZIP file format with an
optional manifest file. The manifest stores meta-information about
the JAR file contents and is also used for signing JAR files.
Package Specification

making the pack stream highly compressible by a compressor such as
gzip or zip.
|
| Pack200.Unpacker |
The unpacker engine converts the packed stream to a JAR file.
