        // Assuming you have installed OpenTelemetry SDK
        use OpenTelemetry\Sdk;
        use OpenTelemetry\Instrumentation\Autoloader;

        // Initialize OpenTelemetry
        $tracerProvider = Sdk::providerBuilder()
            ->setResource(Resource::create([
                'service.name' => 'my-package-registry',
            ]))
            ->buildTracerProvider();

        $tracer = $tracerProvider->getTracer('my-package-registry');

        // Example: Instrumenting a package publish function
        function publishPackage($packageName) {
            global $tracer;

            // Start a new span
            $span = $tracer->startSpan("publish_package");
            try {
                // Your logic to publish the package
                echo "Publishing package: $packageName";
                
                // Simulate package publishing delay
                sleep(1);
            } catch (Exception $e) {
                // Record exception
                $span->recordException($e);
            } finally {
                // End the span
                $span->end();
            }
        }

        // Example usage
        publishPackage('example-package');
