 - **Automated License Discovery and Configuration**
   The new `license-manager` command-line tool automatically queries FlexNet license servers and synchronizes license availability with GCS. It discovers available licenses, creates corresponding GCS complexes with the `lm_` prefix, (configurable) and maintains accurate license counts without manual configuration.
-- **Real-Time License Monitoring**
-  Operating as a GCS load sensor, the license-manager reports current license availability in real-time, allowing the scheduler to make informed job placement decisions based on actual license capacity. This prevents job failures due to license exhaustion and optimizes license utilization across the cluster.

 - **External License Tracking**
-  The tool provides integration for tracking licenses consumed by non-GCS processes, ensuring accurate accounting of total license availability and preventing over-subscription when external applications share the same license pool.

 Authentication can be enabled during installation or via bootstrap configuration changes.
