How to specify entry for .emacs.d ?

Hi

I tried to use this tools to synch my ~/dotfiles directory
I run into problems with my ~/dotfiles/.emacs.d directory - it is jsut ignored
Renaming it to emacs_d and adding a line
emacs_d:emacs.d
results in a link
~/emacs.d
Which is not right.
Changing to
emacs_d:.emacs.d
is also silently ignored.
So how should I specify my .emacs.d folder to make it work?

Cheers,

Daniel
