From a7cb1509317e929043df973a9814145fecc99513 Mon Sep 17 00:00:00 2001 From: Dan McGee Date: Fri, 23 Dec 2011 14:32:01 -0600 Subject: be_package: be more explicit parsing key/value pairs This eliminates the need for strtrim() usage completely, instead relying on the fact that the only allowed delimiter between key and value is the " = " string.
