Upstream provides a .gitattributes file with export-ignore that prevents uscan
from getting some files, like the unit tests.

How to make the debian orig file?
=================================

1. If you are packaging a new version, make sure you have the wanted version in
debian/changelog

2. Create a copy of this working directory, so that upstream tags don't pollute
your git space, then cd in it.

3. Get upstream git
> git remote add upstream https://github.com/phppgadmin/phppgadmin
> git pull upstream

4. Verify upstream tag signature
> gpg --import debian/upstream/signing-key.asc
> git tag -v REL_7-12-1

5. Run git deborig with the upstream tag, something like:
> git deborig REL_7-12-1

6. Strip unwanted files using debian/copyright, something like:
> mk-origtargz --package phppgadmin --version 7.12.1 --repack-suffix +dfsg --rename --compression default --directory .. --copyright-file debian/copyright ../phppgadmin_7.12.1+dfsg.orig.tar.xz
