 The Loggly transport is based on [Nodejitsu's][2] [node-loggly][3] implementation of the [Loggly][0] API. If you haven't heard of Loggly before, you should probably read their [value proposition][4]. The Loggly transport takes the following options. Either 'inputToken' or 'inputName' is required:

 ## Motivation
 `tldr;?`: To break the [winston][1] codebase into small modules that work together.
