 /**
+ * This abstract class represents a common superclass for implementations
+ * of jar URL's.  A jar URL is a special type of URL that allows JAR
+ * files on remote systems to be accessed.  It has the form:
+ * <p>
+ * jar:<standard URL pointing to jar file>!/file/within/jarfile
+ * <p> for example:
+ * <p>
+ * jar:http://www.urbanophile.com/java/foo.jar!/com/urbanophile/bar.class
+ * <p>
+ * That example URL points to the file /com/urbanophile/bar.class in the
+ * remote JAR file http://www.urbanophile.com/java/foo.jar.  The HTTP
+ * protocol is used only as an example.  Any supported remote protocol
+ * can be used.
+ * <p>
+ * This class currently works by retrieving the entire jar file into a
+ * local cache file, then performing standard jar operations on it.
+ * (At least this is true for the default protocol implementation).
