 *			Code cleanups
 *
 * Everybody is tired of writing Forms and so am I. This
 * class is not feature-complete at all, but it keeps you
 * away from writing html-Forms over and over again.
 *
 * Output is formatted into a table of (configurable) width
 * and should be xhtml 1.0 compliant. Appearance of text can
 * be tweaked by editing the style class for .formtext {}
 *
 * Don't forget to use this class for writing html-Forms
 * only in a normalized Form (which means putting error
 * checking and form generation into one file, so that the
 * generated form is presented to the user until correctly
 * filled out.)
 * FIXME: add an english-language link here.
 *
 * See http://www.koehntopp.de/php/faq-code.html#code-5 for
 * examples on good form-processing
 *
 * FIXME: add a class which allows for automatic input
 * checking
 *
 * FIXME: support all Form-Elements from XHTML 1.0
