How to install an existing Drupal profile with drush?

Question

Seems like searching for the answer on Google just leads me to how to create make files and profiles.

I know how to do that. I also know how to install Drupal with drush.

But I want to install one of the many existing Drupal profiles, like Drupal Commons, Commerce Kick Start, etc. with drush.

I would have thought it would have been just an easy process to find the profile's makefile and run that. Drush will take care of the rest. But I can't find the repositories where these makefiles sits.

Some direction would be appreciated.
