Fine. Then I can still agitate for my approach via other means :)

The uses which I have found for this task include the ability to copy
the selected dependencies into a single directory (while optionally
removing the version suffixes). This is very useful for binary
releases, which tend to ship their dependencies. You sort of need the
fileset for that. Otherwise, it is simpler to run from the cached
files.

I agree that it is a problem, and that declaring a central home is a
good idea. And having the ability to redefine the layout of the
repository is very good - I happen to have a case where that is
important for internal dependencies. I would like to understand better
how your approach helps with cross-project issues.

Yup.

I did look at it after submitting my task to that group. Their
approach seemed to be essentially the same as mine, although slightly
less well developed. Of course, I might have missed something - the
project was never very active in the time I was subscribed to the
list.
