     * one from the {@link $_event_stack}, and uses the token event array set up
     * by the class constructor to call event handlers.
     *
     * The event handlers each process the tokens passed to them, and use the
     * {@link _addoutput()} method to append the processed tokens to the
     * {@link $_line} variable.  The word parser calls {@link newLineNum()}
     * every time a line is reached.
     *
     * In addition, the event handlers use special linking functions
     * {@link _link()} and its cousins (_classlink(), etc.) to create in-code
     * hyperlinks to the documentation for source code elements that are in the
     * source code.
