+`otel-handler`
+
+This script is a wrapper around the existing `otel-instrument` script to maintain
+backward compatibility while providing a more descriptive name.
+
+It simply forwards all arguments to the `otel-instrument` script.
+
+Usage
+-----
+Use this script exactly as you would use `otel-instrument`:
+
+.. code::
+
+    AWS_LAMBDA_EXEC_WRAPPER = /opt/otel-handler
+
+END_DOCUMENTATION
+
+# Get the directory where this script is located
+SCRIPT_DIR="$(cd "$(dirname "${BASH_SOURCE[0]}")" && pwd)"
+
+# Call the original otel-instrument script with all passed arguments
+exec "${SCRIPT_DIR}/otel-instrument" "$@"
