+DESCRIPTION
+       The patch for Nvidia vulkan drivers to remove NVENC session limit
+
+       -s             Silent mode (No output)
+       -r             Rollback to original (Restore lib from backup)
+       -h             Print this help message
+       -c VERSION     Check if version VERSION supported by this patch.
+                      Returns true exit code (0) if version is supported.
+       -l             List supported driver versions
+       -d VERSION     Use VERSION driver version when looking for libraries
+                      instead of using nvidia-smi to detect it.
+       -j             Output the patch list to stdout as JSON
