%description
The Moore Threads MTT S30 DKMS package provides automatic kernel module
rebuilding support for the sGPU driver. When a new kernel is installed,
DKMS will automatically rebuild the sgpu_km module to match the new kernel ABI.

This package ensures that the MTT S30 GPU driver remains functional
after kernel updates without manual intervention.

Features:
- Automatic module rebuilding on kernel updates
- Support for multiple kernel versions simultaneously
- Easy uninstallation and cleanup

Note: This package depends on the mtt-s30-driver package which contains
the actual source code.
