# 0.3.36-1: lightweight tag: used for debian packaging.
# git describe (without --tags) should calculate the version
# from the latest annotated tag, not from the lightweight tag.
# calculate version without --tags for git-describe,
# and prepare the lightweight tag fot the name (e.g., 0.3.36-2).
# then we can generate changelog entry for 0.3.36-1..0.3.36-2.
