 * $Log: drv.h,v $
 * Revision 1.2  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
 *
 * Revision 1.1  2004/01/09 17:03:07  reinelt
 * initiated transfer to new driver architecture
 * new file 'drv.c' will someday replace 'display.c'
 * new file 'drv_MatrixOrbital.c' will replace 'MatrixOrbital.c'
 * due to this 'soft' transfer lcd4linux should stay usable during the switch
 * (at least I hope so)
