 Stable API is exposed in [zstd.h].
 Advanced and experimental API is exposed in `zstd_static.h`.
 `zstd_static.h` API elements should be used with static linking only,
 as their definition may change in future version of the library.

+#### Separate compressor and decompressor
+
+To build a separate zstd compressor all files from common/ and compressor/ directories are required.
+In similar way to build a separate zstd decompressor all files from common/ and decompressor/ directories are needed.

 #### Buffered streaming
 
 This complementary API makes streaming integration easier.
 It is used by `zstd` command line utility, and [7zip plugin](http://mcmilk.de/projects/7-Zip-ZStd) :

-- zbuff_static.h
