# Stamp landing footers with version + last content change + linkified commit.
#
# Usage (from koopa-admin-log root):
# ./scripts/taler-landing/stamp-landing-version.sh # re-stamp with HEAD + current version
# ./scripts/taler-landing/stamp-landing-version.sh --bump # version += 1, then stamp HEAD
# ./scripts/taler-landing/stamp-landing-version.sh --set 42 # force version
#
# Typical flow after editing landing HTML/CSS/JS:
# 1) edit landings
# 2) ./scripts/taler-landing/stamp-landing-version.sh --bump
# 3) git add configs/ && git commit
# 4) ./scripts/taler-landing/stamp-landing-version.sh && git add configs/ && git commit --amend --no-edit
#
# Or one-shot (commits for you if GIT_STAMP_COMMIT=1).
