Making application help work for xdg-apps

[Matthias Clasen <matthias clasen gmail com>]

Hi,

I just had a brief discussion with Shaun (the yelp maintainer) about
how to make help work for xdg-apps. I suggested that the easiest way
to make this would be to export the help files out of the bundle so a
yelp outside the sandbox can see them. But now I wonder if we even
need that, at least for a system-installed yelp... did we have a
written-down plan for this, Alex ?
