Drush Make packages module information so you can build a Drupal installation with a set of downloaded modules. By turning the make
file into an installation profile, you can go one step further by enabling modules and preconfiguring the Drupal site, which leads to ready to use Drupal distributions such as Open Atrium (http://openatrium.com), Open Public (http://drupal.org/project/openpublic), or Commons (http://drupal.org/project/commons).
Now we will create our own Drupal distribution. Let's suppose that we have been working on a site for promoting our favorite music festival. There is stuff in this site that we would like to use in future festival websites. We will first install Drush Make and then generate a make
file out of our existing site.
