Hello Sylvain,

sorry for the two months delay...

Even if there is more metadata, this can be included using the right 
syntax. You didn't explain any reason to break with the syntax of yml. 
What do you want to express that can not be expressed with the official 
syntax? The driver to change this, is that anyone can then use an 
exsiting yml parser to work with this files from any ruby script or 
library instead of having to implement any additional rock-config files 
parser.

I accept that you have a fair point on this one but somehow I still 
don't like to have to parse the filename to get to know to which task it 
belongs too... Maybe I just have to get used to it.

Kind regards,
