Thanks Walter. This is a great day!

One rough patch:
Phobos docs don't include the new 'core' modules, except core.memory 
which appears where std.gc used to be.

We also now have two modules called 'bitmanip', which is somewhat ironic 
since we brainstormed for ages trying to come up with a better name for 
it. Modules with duplicate names have caused linking problems in the 
past -- not sure if that applies here.
