Can you please clean the history with this patch (i.e., "Next try" is not a nice git comment). I think that a single commit should be enough. Also describe some details in the patch so that it can be reapplied easily in case something changes. Thank for your contribution.

Sure, I hope this is better now.

[sba1]

Yes, much better! But can you please describe within the gild commit from which version the new files originate from? This helps maintaining it.

[josefwegner]

Okay, gild commit message now includes where you find the new files.

Merged and thanks!
