# Upstream expects a version in format vX.Y.Z, and without this will
# not make a "clean release build" (Bug #1061296).  A better solution
# may be patch build.go script.  At that bug, Simon Frei notes that
# passing '-version <upstream_version' does not successfully inject a
# version, so the best solution is probably to enable that functionality.
#
# At that time Alexandre Viau's ST_DEB_VERSION implementation and
# comment should be resurrected (git commit <= 2df76fd), and mine erased.
