Whenever a contributed module has a new version, Drupal's update manager will show a notification and allow automatic downloading of the updates. After that, the user is guided through "update.php". Is it possible to get the same automatic treatment for custom modules?
If I develop a few custom modules for a specific site, it would be interesting to get Drupal to look for updates of said custom modules, on a server specified by me, where I'm hosting the modules myself, and treat them like any contributed module. But maybe this goes against good practices?
