|
|
* The Log4c library looks for logging configuration files in:
|
|
* ${LOG4C_RCPATH}/log4crc
|
|
* SYSCONFDIR/bongo/log4crc (/opt/bongo/etc. or similar)
|
|
* ./log4crc
|
|
* The example config file for this program has two categories defined,
|
|
* "root" which is the parent for everything (all events bubble to it),
|
|
* and "funtest", a category representing events from this code.
|
|
* "root" is set to output to syslog, but only LOG_FATAL severity messages.
|
|
* "funtest" outputs to stderr, any severity.
|
|
* I would leave these notes in the config file, but Log4c's XML parser
|
|
* seems to choke on comments.
