Well, I prefer to use my own configurations and arbitraty configuration
mappings, even if I *could* abuse maven2 scopes. And I'm pretty
sure that I've already some cases where I really need configuration
mappings, but I'd to check our Ivy repo to be sure. (I should write
a short survey of how we're using Ivy anyways, but that'll take
some time)

Would some kind of include mechanism for sets of default conf mappings
be feasible? Something like

	<dependencies defaultconfmappingset="${some_url_or_file}">

${some_url_or_file} then would define all the conf mappings used.

Since configurations and conf mappings tend to be very policy-driven
(on a per-organisation or per-projectgroup base), this would give
maximum flexibility without hard-wiring some automagic stuff into

Of course, this is just a rough idea; the available configurations
should be defined in ${some_url_or_file}, too, so the dependencies
element probably isn't the best place to include it.
