result of this License or out of the use or inability to use the
Work (including but not limited to damages for loss of goodwill,
work stoppage, computer failure or malfunction, or any and all
other commercial damages or losses), even if such Contributor
has been advised of the possibility of such damages.

# log4js-node
This is a conversion of the [log4js](http://log4js.berlios.de/index.html)
framework to work with [node](http://nodejs.org). I've mainly stripped out the browser-specific code
and tidied up some of the javascript.
## tests
Run the tests with `node tests.js`. They use the awesome [jspec](http://visionmedia.github.com/jspec) - 3.1.3
## usage
See example.js:
var log4js = require('log4js-node');
log4js.addAppender(consoleAppender());
log4js.addAppender(fileAppender('logs/cheese.log'), 'cheese');
var logger = log4js.getLogger('cheese');
logger.setLevel('ERROR');
logger.trace('Entering cheese testing');
logger.debug('Got cheese.');
logger.info('Cheese is Gouda.');
logger.warn('Cheese is quite smelly.');
logger.error('Cheese is too ripe!');
logger.fatal('Cheese was breeding ground for listeria.');
Output
\[2010-01-17 11:43:37.987\] \[ERROR\] cheese - Cheese is too ripe!
\[2010-01-17 11:43:37.990\] \[FATAL\] cheese - Cheese was breeding ground for listeria.
## configuration
You can either configure the appenders and log levels manually (as above), or provide a
configuration file (`log4js.configure('path/to/file.json')`). An example file can be found
in spec/fixtures/log4js.json
## todo
I need to make a RollingFileAppender, which will do log rotation.
patternLayout has no tests. This is mainly because I haven't found a use for it yet,
and am not entirely sure what it was supposed to do. It is more-or-less intact from
the original log4js.
## author (of this node version)
Gareth Jones (csausdev - gareth.jones@sensis.com.au)
## License
The original log4js was distributed under the Apache 2.0 License, and so is this. I've tried to
keep the original copyright and author credits in place, except in sections that I have rewritten
extensively.
