I noticed that a lot of the Flowplayer files use UNIX line endings, whereas some of them use Mac OS 9 CR-only line endings. This breaks a lot of tools like diff. Hence, it's hard for me to see what has changed when changes are made to Flowplayer.

I figured out how to change all the files without breaking anything. I blogged the solution here:http://jjinux.blogspot.com/2009/11/linux-convert-mac-to-unix-line-endings.html . It's actually very simple.
