From dd2b2f0a7bbd1ca44c7834718bbc1f5aae9212ba Mon Sep 17 00:00:00 2001
From: Benjamin Schieder <blindcoder@scavenger.homeip.net>
Date: Tue, 6 Jan 2004 23:34:12 +0000
Subject: [PATCH] Benjamin Schieder <blindcoder@scavenger.homeip.net>: Patch
 Create-ISO to pass the path-specs as a file, not as one command-line
 parameter per file. This enables Create-ISO to create DVD-Images by not
 exceeding the 32k command-line limit.
