# Goal: convert the fresh dsc file to a generic one for obs that omits version and checksum info on filenames
# Use in debian/rules:
#    APPNAME=name-of-binary-package
#    override_dh_auto_build:
#       dh_auto_build
#       /usr/bin/make-dsc-for-obs
# Dependencies:
#    rec-devuan: coreutils
# Must be run in the package tarball dir, where you can find the debian/ dir.
