title: How can I change the winston log format?
body: <p>In my node application I'm using winston module to store my application logs. We can store the the logs in two format one is json and the other one is string. While saving the log as string in winston I'm getting below log format.</p>
  
  <pre><code>  2013-09-10T06:51:34.199Z - error: error message!!!
         (timestamp)     -    (level) : (log message)
  </code></pre>
  
  <p>Now I want change the above log format to the following:</p>
  
  <pre><code>    2013-09-10T06:51:34.199Z/error/error message!!!
         (timestamp)    /     (level) / (log message)
  </code></pre>
  
  <p>How can this be achieved?</p>
  
  <p><strong>My Code</strong>:</p>
  
  <pre><code>  var winston = require('winston');
    winston.loggers.add('category1', {
     file: {
        filename: '/path/to/some/file',json:false
       }
    });              
    var category1 = winston.loggers.get('category1');
    category1.log('error','error message!!!');
