 * Revision 6.4  1996/01/16  20:32:17  sar
 * Ifdefed some used stuff (all the read utilities).
 *
 * Revision 6.3  1996/01/10  16:41:40  sar
 * Usec updates - added a new set of options to the config file
 * for use with the usec agentid, access, context and user info.
 *
 * Revision 6.2  1995/11/11  00:09:41  sar
 * Added a new command option to decide where the rfc1445 viewtree
 * comes from - the config.txt file or nvviews.c

 * Modified the status codes to deal with CAG0.
 *
 * Revision 5.4  1994/11/07  22:16:28  sar
 * Made stdf.h be a local include file, this means we need to copy
 * stdf.h to where ever nvutils.c is (also need stdf.c as well).
 *
 * Revision 5.3  1994/11/01  17:54:49  sar
 * Added a flag to the mod list entry to allow us to determine if the
 * entry was being deleted and therefore shouldn't be written out.

 * in a fprintf statement changed the control string to use %ld instead of %d
 *
 * Revision 5.1  1994/09/23  19:29:50  sar
 * Removed the old non volatile scheme and added a new one that is hopefully
 * easier to use and allows for some new options such as a read only
 * flag to prohibit creating a new config file.  The config stuff will
 * only be included if needed.
 * In snmptalk and snmpint added a next function.
