Many large, successful, de-centralised software projects have a suite of their own packages maintained with their own platform-independent tools. Typical examples are Drupal's collection of module and theme packages, the R Project packages (CRAN) and the Central Repository for Maven packages (Java).
In the case of Drupal:
- Debian only really packages the core Drupal system and not the modules and themes
- Gunnar's dh-make-drupal can easily Debianize many of the modules from Drupal's collection
- Drupal has strict rules about the contents of packages distributed from their official collection. In particular, they must all be 100% compatible with the GPL v2 or later.
This is a particular opportunity for Debian to demonstrate it's strengths.
