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