to be used on anything production, if you want to test it, beware, it may or
may not work (feel free to complain to me if it doesn't work, or shower
praise if it does work)...
Mainly in PHP's CVS so that work on the other backends can take place.
The api (function_entry) is what I'm thinking of for all backends. Every
backend simply needs to define these functions, I'll send an e-mail describing
all this in a bit....
