 ## xxhash
 
-The [xxHash library](https://cyan4973.github.io/xxHash/) provides extremely
-fast checksum functions that can make the "rsync algorithm" run much more
-quickly, especially when matching blocks in large files.  Installing this
-development library adds xxhash checksums as the default checksum algorithm.

 ## zstd
 
-The [zstd library](http://facebook.github.io/zstd/) compression algorithm that
-uses a lot less CPU than the default zlib algorithm at the same compression
-level.  Note that you need at least version 1.4, so you might need to skip the
-zstd compression if you can only install a 1.3 release.  Installing this
-development library adds zstd compression as the default compression algorithm.

-very little CPU, though it also has the smallest compression ratio of other

-checksum routines when computing MD4 & MD5 checksums.
