From 5f4f3f003e1f08e5495e0fe30fae18eb6029888d Mon Sep 17 00:00:00 2001
From: Adrian Kummerländer

Subject: Switched filesystem interaction code to boost::filesystem * while
 plain read access on files is doesn't require boost::filesystem it will
 greatly simplify the implementation of external directory traversal functions
 * it also improves the portability of relative path construction
