How to install Chosen using Drush Make? From Chosen module page:


  This module comes with a Drush make file, which will automatically download the jQuery plugin if you use Drush make to set up your website.


I have Drush Make, but commands like..

 drush dl chosen
 drush en chosen


..don't help.
Should I use drush make ... command instead? Maybe there are other commands for quick libraries download.

P.S. I'm working on already installed copy of Drupal.
I found a way:

# cd to Drupal root folder
drush dl chosen
drush make sites/all/modules/chosen/chosen.make.example --no-core
drush en chosen -y


Update 04/29/2014: Chosen now provides Drush command chosenplugin.  

This answer is still useful for other projects with *.make.example files but without custom Drush installation commands.
