From 09cdbbfcdb6d796884caf294ac24a54be8d82cc3 Mon Sep 17 00:00:00 2001
From: laforge <laforge>

Subject: Major update. Almost everything has changed. - no more dynamic
 allocations at runtime - only once at startup - less list traversal through
 interpreter and key hashes - output plugins can request only certain results!
