* Revision 1.3 2004/01/13 08:18:20 reinelt
* timer queues added
* liblcd4linux deactivated turing transformation to new layout
*
* Revision 1.2 2004/01/11 18:26:02 reinelt
* further widget and layout processing
*
* Revision 1.1 2004/01/10 20:22:33 reinelt
* added new function 'cfg_list()' (not finished yet)
* 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
