%description
Whole-buffer DEFLATE-based compression and decompression of raw vectors
using the 'libdeflate' library (see
<https://github.com/ebiggers/libdeflate>). Provides the user with
additional control over the speed and the quality of DEFLATE compression
compared to the fixed level of compression offered in R's 'memCompress()'
function. Also provides the 'libdeflate' static library and 'C' headers
along with a 'CMake' target and 'package‑config' file that ease linking of
'libdeflate' in packages that compile and statically link bundled
libraries using 'CMake'.
