debug-logger/examples/file.js

A wrapper for visionmedia/debug logger, adding levels and colored output

// Write to a file
// e.g.: node examples/file.js 3>debug.log
process.env.DEBUG_FD=3;

    fatal: {
      color : 5,  //magenta

      namespaceSuffix : ':fatal',
      level : 6
    }
  }
})('myapp');
