+# Publish a new Development beta tag.
+# Wraps the manual flow:
+#   git checkout master && git remote update -p && git pull
+#   git tag <date>-Development-<version>-beta[.N]
+#   git push upstream <tag>
+#
+# Tag convention (see cmake/getversion.cmake):
+#   first beta for a version:  YYYY-MM-DD-Development-X.Y.Z-beta
+#   subsequent betas:           YYYY-MM-DD-Development-X.Y.Z-beta.2, .3, ...
+# Version defaults to the PROJECT VERSION in CMakeLists.txt.
+#
+# Usage:
+#   ./publish_beta.sh [--dry-run] [--yes] [--version X.Y.Z] [--remote upstream] [--branch master]
