From 6377582841118688aee13aff98c9216403582e45 Mon Sep 17 00:00:00 2001 From: Lukas Fleischer Date: Tue, 19 Jul 2011 16:08:17 +0200 Subject: Use map for configuration variable names Use a map instead of dozens of hardcoded conditionals. This makes configuration variable parsing more dynamic and extensible. Also, reintroduce formatting error messages that we dropped earlier.
