Patches to implement this gratefully accepted.  :)  Please include:

* argument handler entry point to allow them to be specified as a setup() 
keyword (I suggest "dependency_links")
* documentation in setuptools.txt for the keyword
* a metadata writer entry point to write the file (you might be able to 
reuse one of the existing entry points
* code in easy_install's process_distribution() function to read and 
process the metadata before doing dependency processing

Thanks.  :)
