Wouldnt a database used only for the purpose of description searches
be relatively easy to implement? after all, the description string
doesnt change based on masking, keywords, installed packages, version
numbers, etc. Thus, most of the dificulty of maintaining the database
is eliminated. Unless I am way off:)

just a thought, but couldn't a database somehow involving the mtimes
be used to decide which files to rsync? I"m not to sure on this, I
just thought it might spark some good ideas.
