I have a lot of experience with the rucksack b-tree code. It is great
code, but once you want to start using it you will want full control
of the file. I don't think a separate project will be fruitful.
Copy/Paste or Kill/Yank is probably better IMO.

Previously Arthur Lemmens said he wanted to minimize dependencies. But
you never know.

Yes, It will be a fast and good start. There are testcases to copy as well.
