There is a newer version available...
Added a way to simple get the orig "source"...

...which actually is a binary build release by upstream and not the source of graylog2
Revert "Dropped some unneded files"

This reverts commit 2613521eaf040cba7a2fbc393b6e9f32d8c092b3.
Dropped a binary debian package laying around in the repo
Added more targets to debian/rules and improved exiting ones
Improved README.md
Do not store the orig.tar.gz on the local system

It is not needed, since this package has format 'native' (which actually is
the wrong format according to the debian policies).
