My pleasure. It is a university project, so quite a lot of people took 
part in it over the years (and will also do so for the foreseeable future).

The packaging was done for our internal purposes: we have some lab 
computers for students and faculty with debian and ubuntu, but of course 
I would love to have in Debian mainline.

The packaging as it is now allows me to install svarog on debian 
systems, but of course some things could be improved. The licensing was 
cleaned up, everything should be compliant (mostly GPL). Also java 
versions shouldn't matter (I haven't done extensive testing, but I used 
both and didn't see any problem).

The big hurdle is the amount of dependencies not in Debian:
- libjmatio-java (this one is very simple),
- libjmx-java (this one is fairly simple too, our own code),
- libjtransforms-java (fairly simple)
- libeega-tag-library-java (our own code, very simple too),
- libbluecove-java (this one is a complex beast, pretty hard to package 
properly. Currently the package is a fake, network is accessed during 
build).

svarog and the others (apart from libbluecove) are nice and simple java 
packages (either maven or ant), already packaged by me. Would it be 
feasible to add 6 packages? The descriptions are missing and there are 
some other small problems, but I wouldn't expect more than a few hours 
of work to get the whole lot lintian-clean. libbluecove would be more 
trouble, but I could give it a go. It is used to support bluetooth 
amplifiers in svarog.

Looks like the university admin removed the hole in the firewall, again.
For some reason port 9148 is so suspicious :)
I think that https is best for external access anyway: slow but secure.

Yeah, it's a bit of a mess. We all use git master anyway, so that's why 
the tags were somewhat forgotten.

Well, thanks for providing such an excellent foundation to built 
software on. It would be extremely cool if we could have Svarog in Debian.

PS. Under https://escher.fuw.edu.pl/debian/ there's a repository will 
debs and source packages.
