Whilst the core libraries don't change that frequently I think
hard-coding is a bad idea, so doing it dynamically would be best IMO,
of course if this takes a long time its undesirable so something that
is dynamic and quick, but perhaps most importantly works.

Which of those that is I counted really tell you though, sorry.

Keep up the good work,
