<P>
The <code>JarInputStream</code> class is used to read the contents of
a JAR file from any input stream. It extends the class
<code>java.util.zip.ZipInputStream</code> with support for reading
an optional <code>Manifest</code> entry. The <code>Manifest</code>
can be used to store meta-information about the JAR file and its entries.
JarInputStream类被用来从任意输入流中读取JAR文件的内容，继承自类java.util.zip.ZipInputStream，支持读取可选的Manifest项。
Manifest被用来存储JAR文件及其项的元信息。
