+Usage: $(basename "$0") [OPTIONS]
+
+Generate GitHub-compatible Markdown release notes for an OBITools4 version.
+
+Options:
+  -v, --version VERSION   Target version (e.g., 4.4.15). Default: latest.
+  -l, --list              List all available versions and exit.
+  -r, --raw               Output raw commit list without LLM summarization.
+  -c, --context           Show the exact context (commits + prompt) sent to the LLM.
+  -m, --model MODEL       LLM model for orla (default: $LLM_MODEL).
+  -h, --help              Display this help message.
+
+Examples:
+  $(basename "$0")                  # release notes for the latest version
+  $(basename "$0") -v 4.4.15       # release notes for a specific version
+  $(basename "$0") -l              # list versions
+  $(basename "$0") -r -v 4.4.15    # raw commit log for a version
