- * $Log: imon.c,v $
- * Revision 1.5 2004/03/03 03:47:04 reinelt
- * big patch from Martin Hejl:
- * - use qprintf() where appropriate
- * - save CPU cycles on gettimeofday()
- * - add quit() functions to free allocated memory
- * - fixed lots of memory leaks
- *
- * Revision 1.4 2004/01/29 04:40:02 reinelt
- * every .c file includes "config.h" now
- *
- * Revision 1.3 2004/01/09 04:16:06 reinelt
- * added 'section' argument to cfg_get(), but NULLed it on all calls by now.
- *
- * Revision 1.2 2004/01/06 22:33:14 reinelt
- * Copyright statements cleaned up
- *
- * Revision 1.1 2003/10/12 06:08:28 nicowallmeier
- * imond/telmond support
