is this script in use by you, or is it abandoned in favor of another idea?

Anyway, I have tried it today but it looks like the top-bases wasn't
updated to the new deps. It points still to the old base. Second, I
got an empty line in my .topdeps file.

IMHO all these "| tr '\n' ' '" aren't needed. bash do the right thing here.
