Expose Enhances on package pages

[Kjetil Kjernsmo <kjetil@kjernsmo.net>]

Hi all!

I'm the upstream author of http://packages.debian.org/sid/librdf-generator-
void-perl and the package maintainer has decided to translate my "recommends" 
for the perlrdf package in the CPAN package to an Enhances in the Debian 
package. Studying Debian's package relationship semantics, I think he's right, 
Debian has a richer package system. However, I think it is a problem users 
aren't made as easily aware of the available enhancements as they are with 
Recommends and Suggest.

So, at the very least, I suggest adding the enhancement to the package pages.

Best, 

Kjetil
