Drupal6features is a project mainly written in PHP, it's free.
Thanks to this feature, I have a Drupal 6 website up and running with all my favorite modules in less than 2 minutes.
This Drupal 6 module helps you to download the most useful modules for Drupal 6 and enable them in a row.
Add this in your .make file to have those modules automatically installed in your distribution:
Example of a working drupal6 makefile:
; A basic Drupal site
core = 6.x
projects[] = drupal
projects[modules_dependency][type] = module
projects[modules_dependency][download][type] = git
projects[modules_dependency][download][url] = git://github.com/Polzme/drupal6features.git
projects[modules_dependency][subdir] = "contrib"
