 * the sword stuff.  It also adds functions to 'print' text from
 * a specified module and to list available modules.
 *
 * All output is in HTML, and unicode characters are not converted
 * to HTML entities (this allows the calling function to decide
 * what encoding to use in the web page e.g. utf 8 could be used
 * and no transformation would need to be done).
