title: Migrate from jsduck to jsdoc
body: <p>I want to migrate lots of JavaScript code which documented with <strong>jsduck</strong> before. and now I want to migrate them all to <strong>jsdoc</strong>.
  It would be great if you help me please. Because I can not find any source for that.
  So, actually I would also prefer to write a script to do this automatically.</p>
