RFC: Method for packaging game data (was Re: Non-commercial redistributable game data)

I've been looking at uqm today to see how we could do this. I did come up with one method that does work (at least in Fedora 13), though it will be a bit of a pain for autodownloader. For uqm, it looks something like this: uqm is in Fedora autodownloader is in Fedora uqm-content is in RPM Fusion Remove Requires: autodownloader from uqm Add Requires: uqm(data) to uqm Add Provides: uqm(data) to autodownloader Add Provides: uqm(data) to uqm-content When installing uqm, if RPM Fusion isn't enabled, autodownloader gets downloaded and installed, and then the game data gets downloaded the first time uqm is run. If RPM Fusion is enabled, yum will prefer uqm-content, which mean uqm will run the first time without needing to download anything. This should consistently work because, in the newer yum versions, one of the tests for choosing which package to install as a dependency is to compare how many letters match (i.e. uqm and uqm-content both start with uqm, while autodownloader doesn't, so uqm-content would be preferred over autodownloader). Do note that there are no conflicts between autodownloader and uqm-content, so there's no problem if someone installs the game without RPM Fusion, thus getting autodownloader, and then enables RPM Fusion and installs uqm-content. The game would proceed to use the content from uqm-content rather than try to download it with autodownloader. The drawback of this method is that, for each game, a new version of autodownloader will have to be pushed with updated Provides *before* we can put the game data in RPM Fusion. Thoughts? Comments? Stones to throw at me? :) Jonathan
