Sometimes... see the archives.

Yes, it takes a tree and builds new .deb files out of it for you.

Could help you out later, yep.

Mmm.  I would expect it to not work.  My build dies when it uses part of itself
in the install:

It looks to me like the problem occurred in frame #3 where
elf_get_dynamic_info was passed `2' as a value.  Bizarrely, this is the
address of a stack variable (take a look in rtld.c), so I am stumped and
I've been working on more interesting stuff instead.  I tried several
times to attract BenC's attention on this and didn't get anywhere.
