Another approach was to use JEBs . This would pack it all in one
archive, so only one file needed. It handles fine the Journal-to-Journal
case. The downside is that you can not easily open it on another machine
until you unzip it first. I am a bit torn what I like more.

I think it is dependent on the case. If we land a fix like this in 0.84
we need to make sure that our users have the same functionality in 0.90.
Of course we can patch 0.90 but other packagers might profit of this,
too. Not sure what dextrose want to do about that issue for example. But
of course the general rule is to only do bug fixes to a released version.
Thanks for the other code based comments. As this is an important issue
that we will have to deal with for a bit longer would be nice to get an
agreement on the approach, that we do not have to change it again in the
