+/*
+ * Class-Path Wildcards
+ *
+ * The syntax for wildcards is a single asterisk. The class path
+ * foo/"*", e.g., loads all jar files in the directory named foo.
+ * (This requires careful quotation when used in shell scripts.)
+ *
+ * Only files whose names end in .jar or .JAR are matched.
+ * Files whose names end in .zip, or which have a particular
+ * magic number, regardless of filename extension, are not
+ * matched.
+ *
+ * Files are considered regardless of whether or not they are
+ * "hidden" in the UNIX sense, i.e., have names beginning with '.'.
+ *
+ * A wildcard only matches jar files, not class files in the same
+ * directory.  If you want to load both class files and jar files from
+ * a single directory foo then you can say foo:foo/"*", or foo/"*":foo
+ * if you want the jar files to take precedence.
+ *
+ * Subdirectories are not searched recursively, i.e., foo/"*" only
+ * looks for jar files in foo, not in foo/bar, foo/baz, etc.
+ *
+ * Expansion of wildcards is done early, prior to the invocation of a
+ * program's main method, rather than late, during the class-loading
+ * process itself.  Each element of the input class path containing a
+ * wildcard is replaced by the (possibly empty) sequence of elements
+ * generated by enumerating the jar files in the named directory.  If
+ * the directory foo contains a.jar, b.jar, and c.jar,
+ * e.g., then the class path foo/"*" is expanded into
+ * foo/a.jar:foo/b.jar:foo/c.jar, and that string would be the value
+ * of the system property java.class.path.
+ *
+ * The order in which the jar files in a directory are enumerated in
+ * the expanded class path is not specified and may vary from platform
+ * to platform and even from moment to moment on the same machine.  A
+ * well-constructed application should not depend upon any particular
+ * order.  If a specific order is required then the jar files can be
+ * enumerated explicitly in the class path.
+ *
+ * The CLASSPATH environment variable is not treated any differently
+ * from the -classpath (equiv. -cp) command-line option,
+ * i.e. wildcards are honored in all these cases.
+ *
+ * Class-path wildcards are not honored in the Class-Path jar-manifest
+ * header.
+ *
+ * Class-path wildcards are honored not only by the Java launcher but
+ * also by most other command-line tools that accept class paths, and
+ * in particular by javac and javadoc.
+ *
+ * Class-path wildcards are not honored in any other kind of path, and
+ * especially not in the bootstrap class path, which is a mere
+ * artifact of our implementation and not something that developers
+ * should use.
+ *
+ * Classpath wildcards are only expanded in the Java launcher code,
+ * supporting the use of wildcards on the command line and in the
+ * CLASSPATH environment variable.  We do not support the use of
+ * wildcards by applications that embed the JVM.
