Currently upstream does not provide any release tarballs
or release tags in git. Thus the .orig.tar.gz provided in
the Debian archive is manually cut from the upstream git
repository. E.g.

    v=$(grep __VYM_VERSION src/version.h | cut -d'"' -f 2); \
    git archive --format=tar.gz -o ~/debian/vym-${v}.tar.gz \
        --prefix=vym-${v}/ HEAD && \
    echo "Archive vym-${v}.tar.gz commit $(git rev-parse HEAD)"

and imported with `gbp import-orig ../vym-2.9.27.tar.gz`.
