People give it a shot, depending on free time and interests. Johannes
used to maintain it originally, maintained additionally by the people
whom you have said above.

Uh oh. trampled again on that. Since we don't have the headers we can
remove that line in the README as well.
But there is high chance that we might need them back, with regards to
API changes for new delivery systems.

We will need another release, but of course there are imminent pending
changes, which are held up due to some reason or the other. A newer
release can go hand in hand alongwith that, else we would need another
release alongwith those changes again.

Currently, the historical stuff is held in util/szap and the newer
zapper is in util/zap
If we were to merge in szap directory alongwith the zap directory , that
would cause some additional confusion ?

libdvbapi2.0 ? currently it is just at version 1. We have not made an
official release on it yet.

scan is the original historical one (IIRC, Holger wrote it). There are
many issues that which pertains to it. adq started up to fix it by
writing a new dvbscan, which was not completed yet, AFAIK. ie, some more
work is needed in there.

Sure, can you give it a shot ?

executables such as dvbscan atscscan and scan in one directory might
make it look a bit confusing ?

i think of something better, once dvbscan is complete, we can move szap
and scan into another folder than the top level one, such that they too
do exist (as i mentioned earlier, these apps are good for quick hacks)
rather than completely removing them.
