%description
Intel(R) Software Guard Extensions (Intel(R) SGX) is an Intel technology for application 
developers seeking to protect select code and data from disclosure or modification.

The Linux SGX software stack is comprised of the Intel(R) SGX driver, the Intel(R) SGX 
SDK, and the Intel(R) SGX Platform Software. The Intel(R) SGX SDK and Intel(R) SGX PSW
are hosted in the linux-sgx project.

The linux-sgx-driver project hosts the out-of-tree driver for the Linux Intel(R) SGX 
software stack, which will be used until the driver upstreaming process is complete.
