+# This script determines the version numbers used in builds and releases.
+#
+# It sets three environment variables:
+#   - PKG_VER   → The package version (semantic version).
+#   - BUILD_VER → The build identifier (may include build number).
+#   - PYPI_VER  → A PyPI-compatible version string for publishing.
+#
+# Behavior:
+#   - On a tagged commit (e.g. "v1.2.3"), it uses that tag as the version.
+#   - On an untagged commit, it generates a "next dev version" by:
+#       • Taking the latest tag (default v0.0.0 if none).
+#       • Incrementing the minor version.
+#       • Appending "+<run number>".
+#   - PYPI_VER is derived from BUILD_VER by replacing "+" with ".dev".
+#
+# This ensures that:
+#   - Release builds (tags) get clean versions like "1.2.3".
+#   - Development builds get versions like "1.3.0+45" (PyPI: "1.3.0.dev45").

+    minor=$((minor + 1))
+
+    # Construct the package version: <major>.<minor>.0

+
+    # Append the GitHub Actions run number for uniqueness

+# Derive PyPI-compatible version
+# PyPI does not accept "+" in versions, so replace with ".dev"
+# Example: "1.3.0+45" → "1.3.0.dev45"
+# -------------------------------------------------------------
