Databox!
The frontend plugin for the searchengine, creates searchengine files (rsp) Its not pretty, but it works. Only compiling for recorder and iriver for now....since i don't know about players... Also, i'm hoping someone will beautify the interface someday. PS. Editing modes aren't fully operational yet. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@6432 a1c6a512-1295-4272-9138-f99709370657
