 * Moved the common string functions from stdf to common/lib and created
 * a series of macros for this code to use
 * Moved strdup to snark/lib and renamed it to etc_strdup to avoid
 * needing one from the system libraries
 *

 * Added global arguments for v3 along with their defaults
 *
 * Revision 7.9  1998/02/25 15:21:58  sra

 * move from envoy/utils to snark/snmptalk

 * Updated rev to 7.0 and copyright to 96
 *
 * Revision 6.4  1996/01/26  22:05:01  sar

 *

 * packet dumping on & off while snmptalk is running.
 *
 * Revision 5.3  1994/11/09  01:43:52  sar
 * Read the nv config file if/when we need to.  If the master_agent or
 * v2_view options are installed we always read it, if they aren't vut
 * v2 is installed we check the snmptalk_version flag if it is 2 we read
 * the file if it is 1 we don't.  The first time we switch to v2 we
 * try and read the file and complain if one doesn't exist.  If we only
 * have v1 installed we never read the config file.
 *
 * Revision 5.2  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.

 * Added declarations for spoid, dpoid and cpoid (source and dest parties and
 * context oids) and their lengths (spoidlen, dpoidlen and cpoidlen).
