Well, we've been talking before about adding a module in order to save
config or data informations in a persistent storage (such as a file) but we
couldn't agree on which was best. IMHO we need a hierarchical format with
some structural semantics and a minimum of typing , all of that storable in
an text only user editable format. XML would be enough even if not best
before it's widely use and easy to interface with other programming language
for data exchanges. I think CDB is not enough powerful - although
convenient - so that we reach an agreement on it.
