Comment 4 for bug 1450459

Thanks, Roberto. As it is now, Variety is packaged for installation as an Ubuntu "extra" and this type of package is posted to the PPA. This is a legacy from the way Variety started as a project in the beginning, as part of an Ubuntu-specific competition.
One of the next official releases will change this, and Variety will be packaged in the standard Debian way, so this bug will become obsolete (hopefully...).

As it is now, the debian rules file is autogenerated as part of the build process (with a tool called Quickly), so there is no use of changing it directly.
