How should I do object serialization?

[Enjoys Math via Digitalmars-d-learn]

I'm not looking for anything advanced, just serialization of some 
of my own types (classes & structs).

I've seen:
http://wiki.dlang.org/Review/std.serialization
However, I don't see std.serialization in my dmd source tree:
v2.070.0-b2

So where is the /official/ home for D object serialization?

Thanks.
