LMS Quirks, Issues, and Work- Arounds : LRN Learning System

We just had a conversation with one of our clients regarding the fact that out content package would not launch in the LRN LMS. Well the package passed the ADL Conformance Test Suite 1.2.7 and ran on Mike Rustici's Test Track (www.scorm.com) so I was a bit perplexed. After some discussion and emails it came down to the fact that the LRN system requires a file called csd.txt to be placed at the root of the package ALONG WITH the imsmanifest file. It uses this file to find the launch page for the course. This raises the question, what does it do with the manifest file and what does it do if there are multiple SCOs in the content package?

I will post a sample of the csd.txt file soon.....
