 +/*******************************************************************************************************
 +  Introduction
 +
 +  Zstd, short for Zstandard, is a fast lossless compression algorithm, targeting real-time compression scenarios
 +  at zlib-level and better compression ratios. The zstd compression library provides in-memory compression and
 +  decompression functions. The library supports compression levels from 1 up to ZSTD_maxCLevel() which is 22.
 +  Levels from 20 to 22 should be used with caution as they require about 300-1300 MB for compression.
 +  Compression can be done in:
 +    - a single step (described as Simple API)
 +    - a single step, reusing a context (described as Explicit memory management)
 +    - repeated calls of the compression function (described as Streaming compression)
 +  The compression ratio achievable on small data can be highly improved using compression with a dictionary in:
 +    - a single step (described as Simple dictionary API)
 +    - a single step, reusing a dictionary (described as Fast Dictionary API)
 +
 +  Advanced and experimantal functions can be accessed using #define ZSTD_STATIC_LINKING_ONLY before including zstd.h.
 +  These APIs shall never be used with a dynamic library. 
 +  They are not "stable", their definition may change in the future. Only static linking is allowed.
