Subject Re: Passing results of view onto an external
Date Thu, 02 Apr 2009 13:15:02 GMT
Hi Adam,

I'm working on exactly such a feature. It'll loop through a view
result-set and query an external script if a document should make it
into the final output or not.

I hope to get some code out this weekend, but it'll be alpha quality and
definitely not ready for general consumption.
