/**
 * This package provides methods to read files from a JAR file and to
 * transform them to a more compact transfer format called Pack200.
 * It also provides methods to receive the transmitted data and expand
 * it into a JAR file equivalent to the original JAR file.
 *
 * <p>
 * The {@code pack} methods may be used by application developers who
 * wish to deploy large JARs on the web.  The {@code unpack} methods
 * may be used by deployment applications such as Java Web Start and
 * Java Plugin.
 *
 * <p>
 * In typical use, the packed output should be further compressed
 * using a suitable tool such as gzip or
 * {@code java.util.zip.GZIPOutputStream}.  The resulting file (with
 * a suffix ".pack.gz") should be hosted on a HTTP/1.1 compliant
 * server, which will be capable of handling "Accept-Encoding", as
 * specified by the HTTP 1.1 RFC2616 specification.
 *
 * <p>
 * <b>NOTE:</b> It is recommended that the original ".jar" file be
 * hosted in addition to the ".pack.gz" file, so that older client
 * implementations will continue to work reliably.  (On-demand
 * compression by the server is not recommended.)
 *
 * <p>
 * When a client application requests a ".jar" file (call it
 * "Large.jar"), the client will transmit the headers
 * "Content-Type=application/x-java-archive" as well as
 * "Accept-Encoding=pack200-gzip".  This indicates to the server that
 * the client application desires an version of the file encoded with
 * Pack200 and further compressed with gzip.
 *
 * <p>
 * The server implementation will typically check for the existence of
 * "Large.pack.gz".  If that file is available, the server will
 * transmit it with the headers "Content-Encoding=pack200-gzip" and
 * "Content-Type=application/x-java-archive".
 *
 * <p>
 * If the ".pack.gz" file, is not available, then the server will
 * transmit the original ".jar" with "Content-Encoding=null" and
 * "Content-Type=application/x-java-archive".
 *
 * <p>
 * A MIME type of "application/x-java-pack200" may be specified by the
 * client application to indicate a ".pack" file is required.
 * However, this has limited capability, and is not recommended.
