Hi,
Shouldn't tools/wineprefixcreate copy a sample config file?
Right now it does all the job to create a standalone wine environment, but with no config.
I would suggest copying documentation/samples/config to tools/config, installing it at $(SRCDIR) and them just copying it during wineprefixcreate call.
I can do that if no one disagrees with the change.
Some rpms in the sourceforge does not even have the sample config file in it.
