Hmm, I would not trust the dwu script that is up there yet, it hasn't taken into account some things I have found. (needing to be on an originating branch, etc). I've never used those scripts myself. So I think doing it by hand and seeing how it happens is ideal for now.

I went through the Dev Maintenance first section and changed things based on my experiences. Basically, since you should be doing your changes on their own branches, you'll need to checkout the main develop branch, and then pull from the Dreamwidth repository, then push it back to your Dreamwidth fork. If you could look at the changes I made and see if they make sense, I would much appreciate it.
