+Usage: $SCRIPT_NAME [OPTIONS]
+
+Determine the next version number for util-linux releases based on git tags and current branch.
+
+Options:
+ --rc Generate next release candidate version
+ --release-master Generate final major release version (vX.Y)
+ --release-update Generate maintenance release version (vX.Y.Z)
+ --last-release TAG Override last release tag (for testing)
+ --last-xy-release TAG Override last X.Y release tag (for testing)
+ -h, --help Show this help message
+
+Version Schema:
+ Major releases: vX.Y-rc1, vX.Y-rc2, [vX.Y-rc3], vX.Y
+ Maintenance releases: vX.Y.Z-rc1, vX.Y.Z
+
+Notes:
+ - Only stable/* branches are used for releases
+ - Version tags are always prefixed with "v"
+ - X.Y is frozen within a stable branch
+ - Z increments for maintenance releases (vX.Y.1, vX.Y.2, etc.)
+ - Release candidates are optional, created only when --rc is specified
