Personally i dont mind how source is provided as long as it is in a reasonable
way ...
but, when i click on:
"CVS download instructions" i reach a page telling me
"You must read this carefully and agree to it all before you can download the software on this site. "
I dont have to agree to the LGPL or any of the other hundread licenses
on that page. This does not exempt them from the requirement of providing
the source to me (if i had the binary that is)!

oddly viewcvs is not behind such clickthrough, but i failed to find any
ffmpeg code in there, anyone knows in which directory/file it is?
