Thank you  -- that's what I wanted to know.

Could you give a brief description of how the merging of rules works?  
For example, calling omake from a subdir results in parent omakefiles being 
read, but the rules don't get merged.  However in the parent dir merging 
occurs.  (This, of course, is what one would want ...)

Thanks.
