Make hellanzb provide unrar functionality by default

Note that without this dependency, hellanzb will not start up. This is not simply a matter of unraring convenience. So hellanzb as it is must depend on unrar to function at all. However, I see that hellanzb is in universe and unrar is in multiverse; perhaps this is the reason that unrar is not depended upon.

Attached, please find a patch that allows hellanzb to function without unrar installed. If SKIP_UNRAR is set to True, as it is by default in the Ubuntu-distributed hellanzb.conf, the unrar check is skipped since it will never be needed.

This is also blocking all the programs using HellaNZB (LottaNZB, Hellafox...), and should be fixed soon, either by providing a free unrar package, or disabling the 'unrar' feature in /etc/hellanzb.conf .

Depends: par2 (>= 0.4), python (>= 2.3), python-support (>= 0.7.1), python-twisted-core (>= 2.0), python-twisted-web
Recommends: python-yenc
Suggests: unrar (>= 3.41)

Move unrar from suggests to depends.

I've sent the patch by karthik to the maintainer of the hellanzb package along with other minor changes. While adding unrar to the dependencies of hellanzb would probably be the wisest choice from a the user's point of view, I support the decision of the maintainer to leave the installation of unrar up to the user and therefore keeping the package in main (or universe in Ubuntu). Someone who knows how to edit the HellaNZB configuration file will most probably know how to install unrar. And SKIP_UNRAR has been set to True for quite a long time anyway.

As for LottaNZB, we'll probably make sure that SKIP_UNRAR is automatically set to False if unrar is installed and provide a useful hint to the user if not. This will also close http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=523851 LottaNZB was suggested to be moved to contrib.

The bug that caused HellaNZB to crash when unrar isn't installed (no matter what SKIP_UNRAR is set to) has been fixed in Debian. The change will by synced into Ubuntu in a matter of days.

See the above comment for my thoughts about unrar being a default dependency. May I close the bug or are there any other thoughts about this issue?
