.\"O The ucd-snmp package uses various configuration files to configure its 
.\"O applications.  This manual page merely describes the overall nature of 
.\"O them, so that the other manual pages don't have to.

.\"O First off, there are numerous places that configuration files can be
.\"O found and read from.  By default, the applications look for
.\"O configuration files in the following 3 directories, in order:
.\"O /usr/share/snmp, /usr/lib/snmp, and $HOME/.snmp.

.\"O In each of these

.\"O and .local.conf (reading the second on last).  In this manner, there are 6 
.\"O default places a configuration file can exist for any given
.\"O configuration file type.

.\"O Each application may use multiple configuration files, which will
.\"O configure various different aspects of the application.  For instance, 
.\"O the SNMP agent (snmpd) knows how to understand configuration
.\"O directives in both the snmpd.conf and the snmp.conf files.

.\"O .SH "SWITCHING CONFIGURATION TYPES IN MID-FILE"

.\"O It's possible to switch in mid-file the configuration type that the
.\"O parser is supposed to be reading.  Since that sentence doesn't make
.\"O much sense, lets give you an example: say that you wanted to turn on
.\"O packet dumping output for the agent by default, but you didn't want to
.\"O do that for the rest of the applications (ie, snmpget, snmpwalk, ...).
.\"O Normally to enable packet dumping in the configuration file
.\"O you'd need to put a line like:
¥Ñ¡¼¥µ¡¼¤¬Æɤ߹þ¤àÀßÄ꥿¥¤¥×¤Ï mib ¥Õ¥¡¥¤¥ë¤ÎÃæ¤ÇÀÚ¤êÂؤ¨¤ë¤³¤È¤¬¤Ç¤­¤ë¡£

.\"O But, this would turn it on for all of the
.\"O applications.  So, instead, you can put the same line in the
.\"O snmpd.conf file so that it only applies to the snmpd demon.  However,
.\"O you need to tell the parser to expect this line.  You do this by
.\"O putting a special type specification token inside a [] set.  In other
.\"O words, inside your snmpd.conf file you could put the above snmp.conf
.\"O directive by adding a line like so:
