Sorry you're running into the issue with size of the meta data, that 
does need to be fixed, hopefully over the next few months. I wouldn't 
object to compressing the config file in the short term. As regards 
SimpleLibrary then it will likely evolve, maybe in the future there will 
be other Library implementations too.
