 * Revision 1.5  2003/08/24 05:17:58  reinelt
 * liblcd4linux patch from Patrick Schemitz
 *
 * Revision 1.4  2003/08/08 06:58:06  reinelt
 * improved forking
 *
 * Revision 1.3  2001/03/12 12:39:36  reinelt
 *
 * reworked autoconf a lot: drivers may be excluded, #define's went to config.h
 *
 * Revision 1.2  2001/03/09 13:08:11  ltoetsch
 * Added Text driver
 *
 * Revision 1.1  2000/11/28 20:20:38  reinelt
 *
 * added debug.c
 * things like that should not hapen. debug.c exists for a few months now, but was never added to CVS. Shit happens....
