Which is the main reason that this glep has been on a hold for quite some 
time. Nick doesn't want to add xml parsing code so we currently don't 
have such data in metadata.xml.

Parsing metadata.xml for search is actually easier than parsing ebuilds 
for the same (there are more ebuilds to start with). One could even use 
grep as a preselection feature to faster get candidates in which to look 
better (read actually parse the xml).
