 * - fixed lots of memory leaks
 *
 * Revision 1.9  2004/02/01 19:37:40  reinelt
 * got rid of every strtok() incarnation.
 *
 * Revision 1.8  2004/02/01 18:08:50  reinelt
 * removed strtok() from layout processing (took me hours to find this bug)
 * further strtok() removind should be done!

 * liblcd4linux deactivated turing transformation to new layout
 *
 * Revision 1.4  2004/01/12 03:51:01  reinelt
 * evaluating the 'Variables' section in the config file
 *
 * Revision 1.3  2004/01/11 18:26:02  reinelt

 *
 * Revision 1.2  2004/01/11 09:26:15  reinelt
 * layout starts to exist...
 *
 * Revision 1.1  2004/01/10 20:22:33  reinelt

 * added layout.c (will replace processor.c someday)
 * added widget_text.c (will be the first and most important widget)
 * modified lcd4linux.c so that old-style configs should work, too
