+supports BEVE and CSV as well.
 
-%description devel %{_description}
+Glaze utilizes SIMD (SSE/AVX/NEON) and deals well with
+out-of-sequence data and missing keys. Based on an August 2024
+measurement on an Apple M1 CPU, it was measured at 1224/1366 MB/s,
+outperforming other implementations like yyjson-0.10.0 by 10/35%% and
+rapidjson-1.1.0 by 172/371%% (read/write speeds, respectively).
