+%description
+%{summary}
+The SIMDe header-only library provides fast, portable implementations of SIMD
+intrinsics on hardware which doesn't natively support them, such as calling
+SSE functions on ARM. There is no performance penalty if the hardware supports
+the native implementation (e.g., SSE/AVX runs at full speed on x86,
+NEON on ARM, etc.).
