This is a example of a very lightweight, stream based, node.js logger. It creates a "record" object for each log call, and pipe it throught the spicified streams. In the streams its possible to modifie the record, format the message, and many more.

Bunyan, there is no one responding on issues, Winstons is way to big and have unecesseray dependencies.

I wanted a lightweight, easy to use, expandable, stream based, logging utily with zero dependencies. You can all merge this down into a single file. You bascily need class.logger.js & levels.js which can simple merged into a single file.

The other files (demo.js, formatter.js) are for demonstration & formatting and not needed for the functionality.
