Debreate – How to use it?

I’m trying to use Debreate 0.6.5-1 on Ubuntu 10.04 to build a package. I’m new to package building. Can you help with where I’m going wrong?

I have some comments on Debreate:

I can’t find a tutorial. Looks like a great program. But it’s not obvious how to use it.
I’d like an option that takes a whole tree – like Packin does – and builds the package from that. The features that are present look interesting, but are not clear and may not match my requirements, whereas, the Packin method would seem to work for all requirements.
Does Debreate build a .desktop file, or require that you have one? If it builds one that’s great. But I couldn’t get that far since the build failed. Not clear how to do a build, or what those paths are. Error is obviously not very helpful.
It’s complex to fill out all the tabs in Debreate, and I’m likely to want to build a package many times to test it. How about the ability to save ALL the information in the tabs to a file. I thought that’s what the control file was until I looked at it. Maybe the control file could contain “Comments” that contained the rest of the information if the control file is for something else. Maybe the control file is used by the package installer, but that was never clear, since the use of Debreate appears to assume that I know all about packages before I start.

Thanks,
