obsolete comment

[stefan-webrtc, 2017/08/29 08:37:17]

I don't know if it's obsolete to be honest, not clear what Config it refers to.
:)

I'll delete it since it's hard to understand anyway.

Add another comment here, or file an issue, that the contents of this file
should be split out.

[stefan-webrtc, 2017/08/29 08:37:17]

I had to split them already because of dependency issues.
