There seems to be no publicly documented information about how to get applications included in the Canonical Partners repo.
- How does an app/software get included there?
- What are the benefits?
- Do apps need to pay Canonical for inclusion in that repo? (if so, all the app dev needs to do is just pay for the service, no matter what the standard/popularity/usefulness of the app is, it gets included?)
Note: this is about applications in http://archive.canonical.com/ubuntu repo and not the Independent repo (http://extras.ubuntu.com/ubuntu) which falls under the App Review Process.
