[Live-demo] Fwd: Packaging and project re-organization

[Johan Van de Wauw]

Angelos,

I'm very much in favor. Well I actually made similar proposal before.

Do we have an overview of which packages are not yet packaged in .deb files?

Perhaps we can setup some IRC coaching sessions for people to get
started with packaging.
