+Usage: $0 [OPTIONS]
+
+Check ABI compatibility between two versions of libfuse.
+
+OPTIONS:
+    --prev-tag <tag>        Previous release tag/hash to compare against
+                           (default: auto-detect latest release tag)

+
+    --previous-dir <path>   Path to previous version checkout
+                           (default: create temporary checkout at --prev-tag)
+
+    -h, --help             Show this help message and exit

+EXAMPLES:
+    # Auto-detect previous release and create temporary checkouts
+    $0
+
+    # Compare against a specific tag
+    $0 --prev-tag fuse-3.16.2
+
+    # Use existing checkout directories (useful in CI)
+    $0 --current-dir ./current --previous-dir ./previous
+
+NOTES:
+    - If both --current-dir and --previous-dir are provided, the script will use
+      those directories directly without creating temporary checkouts.
+
+    - If only --prev-tag is provided (or auto-detected), the script will create
+      temporary checkouts in /tmp for both versions.
