1520Extensions that define extra resource or command line arguments also need
1521to call this method to access their values.
1522
1523If the method is called on an extension object (basically, from an
1524extension), then the special prefix C<%.> will be replaced by the name of
1525the extension and a dot, and the lone string C<%> will be replcaed by the
1526extension name itself. This makes it possible to code extensions so you
1527can rename them and get a new set of commandline switches and resources
1528without having to change the actual code.
