Re: Inserting content and metadata separately with FCP?

Okay so the basic problem here is that ClientPutComplexDir doesn't allow

https://bugs.freenetproject.org/view.php?id=2672

Sorry that this will not be addressed immediately ... we have some broken but 
potentially very useful code in trunk, and some major problems with the 
network at large, and we need to deal with them...
