Official Debian Package Files in Contrib
After I read carefully the Debian Policy[1] and other references [2] [3], I don't see any problem to upload the debian files inside the upstream source code while it's in another directory than root folder.
The files are the latest version. The package 1.8.1 is waiting for upload.
