Where are the docs for this?

http://dlang.org/phobos-prerelease/index.html

doesn't show anything about sys in core.

I remember seeing somewhere that win32 api was included in dmd 
but that it wasn't working and was suppose to be updated. I would 
like to try it out but I can't find any working information about 
it.

If I add `import core.sys.windows;`

Dmd says `Error: module windows is in file 'core\sys\windows.d' 
which cannot be read`.

I am using DMD Beta 2.070.0-b2

Thanks.
