 * \section API API Reference Usage
 *
 * <h3>C++ Programmers:</h3>
 * <p>Use <a href="hierarchy.html">Class Hierarchy</a> or <a href="classes.html"> Alphabetical List </a>
 * or <a href="annotated.html"> Compound List</a>
 * to find the class you are interested in. For example, to find BreakIterator,
 * you can go to the <a href="classes.html"> Alphabetical List</a>, then click on
 * "BreakIterator". Once you are at the class, you will find an inheritance
 * chart, a list of the public members, a detailed description of the class,
 * then detailed member descriptions.</p>
 *
 * <h3>C Programmers:</h3>
 * <p>Use <a href="#Module">Module List</a> or <a href="globals.html">File Members</a>
 * to find a list of all the functions and constants.
 * For example, to find BreakIterator functions you would click on
 * <a href="files.html"> File List</a>,
 * then find "ubrk.h" and click on it. You will find descriptions of Defines,
 * Typedefs, Enumerations, and Functions, with detailed descriptions below.
 * If you want to find a specific function, such as ubrk_next(), then click
 * first on <a href="globals.html"> File Members</a>, then use your browser
 * Find dialog to search for "ubrk_next()".</p>
