%description
JNI bindings for Zstd native library that provides fast and high compression
lossless algorithm for Android, Java and all JVM languages. It features:
* static compress/decompress methods
* implementation of InputStream and OutputStream for transparent compression of
  data streams fully compatible with the "zstd" program.
* minimal performance overhead
