The issue isn't what can be done, it's how it should be done.
And I'm wary of just dumping everything into one file, even if it's
totally unrelated, simply because of the deficiencies of the source
code control system in use, or the time taken to extract informatino
from a tar archive.

of directories (files/ in most cases), you are cutting out a major part
of the work that is done.

We shall be implementing the diffs I posted previously to this list (and
to other interested parties) RSN. It will be more efficient than what we
