liblzf-dev 3.6-4 (armhf binary) in ubuntu mantic

 This library implements the very, very fast LZF compression algorithm written
 in C. Compression ratios are moderate with 40 to 50 percent for typical
 binary data, but decompression speed is basically at unoptimized memcpy
 speed.
 .
 This package installs the necessary files to develop and link against
 the library.
