I think your understanding of our usage of BDB is rather sufficient.
It certain is one of the simplest database usages I've ever laid eyes
on.

I can't answer for Greg, but were I about to change libsvn_fs to be
pluggable with different database systems, I feel pretty certain I'd
make skels specific to if not Berkeley, at least all database systems
whose values are pretty much limited to a single variable-length text
glob. Skels would be a sort of transport packaging scheme for taking
what *should* be multiple columns of data and stuffing them into a
single column. The directory/file interface might be another such
place to use skels.
