# upstream labels version like "2.1" and "2.1b", or "1.9.6" and "1.9.6c", with
# the latter being parsed as a pre-release/beta by pacman vercmp, and thus not
# being considered an update of the former.  The pkgver scheme I have chosen
# to adopt to solve this issue now:
# - differs minimally from upstream
# - properly signals updates to pacman/AUR helpers, and
# - looks absolutely horrible. I am truly sorry.
# On upgrade, remember to bump $pkgver *and* $_pkgver_upstream.
