Here's what I was talking about... this is the core engine, obviously
it should take some command arguments, and make some intelligent guesses
about where .lrp files exist (stealing from apkg/lrcfg), but I wanted
to show actual working code to make this a non-academic pitch.
Even if folks don't like the idea of dynamic modules extraction at start,
this is a useful tool in its current condition for building up your
modules on demand and saving them with lrcfg.
