Re: Checkout filtering wanted

I agree with Ximon. Again, not knowing anything about the feature
other than what Ben mentioned...having to explicitly specify
directories to check out will either a) be used only for very trivial
and temporary filtering, or b) be something that would be utilized by
a wrapper mechanism that would somehow create on the fly the list of
directories to check out based on external criteria (often utilizing
svn's properties).

The property based filtering I propose seems to me to be a more
powerful, and yet also simpler and more elegant a solution. It would
be capable of doing complex filtering without the need to write
external tools. The name-based mechanism could even be folded into
the --filter mechanism by having a "meta property" that specified the
object's name or path, thereby allowing queries on names as well.

Per Ben's suggestion, I'm going to try to speak with Ben Reser about
