-LZ4 - Library Files 
-================================ 
- 
-The `/lib` directory contains many files, but depending on project's objectives,

- 
-#### Minimal LZ4 build 
- 
-The minimum required is **`lz4.c`** and **`lz4.h`**, 
-which provides the fast compression and decompression algorithms. 
-They generate and decode data using the [LZ4 block format]. 
- 
- 
-#### High Compression variant 
- 
-For more compression ratio at the cost of compression speed, 
-the High Compression variant called **lz4hc** is available. 
-Add files **`lz4hc.c`** and **`lz4hc.h`**. 
-This variant also compresses data using the [LZ4 block format], 
-and depends on regular `lib/lz4.*` source files. 
- 
- 
-#### Frame support, for interoperability 
- 
-In order to produce compressed data compatible with `lz4` command line utility, 
-it's necessary to use the [official interoperable frame format]. 
-This format is generated and decoded automatically by the **lz4frame** library. 
-Its public API is described in `lib/lz4frame.h`. 
-In order to work properly, lz4frame needs all other modules present in `/lib`, 
-including, lz4 and lz4hc, and also **xxhash**. 
-So it's necessary to include all `*.c` and `*.h` files present in `/lib`. 
- 
- 
-#### Advanced / Experimental API 
- 
-Definitions which are not guaranteed to remain stable in future versions, 
-are protected behind macros, such as `LZ4_STATIC_LINKING_ONLY`.

-Should they be nonetheless needed, it's possible to force their publication 
-by using build macros `LZ4_PUBLISH_STATIC_FUNCTIONS` 
-and `LZ4F_PUBLISH_STATIC_FUNCTIONS`. 
- 
- 
-#### Build macros 
- 
-The following build macro can be selected to adjust source code behavior at compilation time : 
- 
-- `LZ4_FAST_DEC_LOOP` : this triggers a speed optimized decompression loop, more powerful on modern cpus. 
-  This loop works great on `x86`, `x64` and `aarch64` cpus, and is automatically enabled for them. 
-  It's also possible to enable or disable it manually, by passing `LZ4_FAST_DEC_LOOP=1` or `0` to the preprocessor. 
-  For example, with `gcc` : `-DLZ4_FAST_DEC_LOOP=1`, 
-  and with `make` : `CPPFLAGS+=-DLZ4_FAST_DEC_LOOP=1 make lz4`. 
- 
-- `LZ4_DISTANCE_MAX` : control the maximum offset that the compressor will allow. 
-  Set to 65535 by default, which is the maximum value supported by lz4 format. 
-  Reducing maximum distance will reduce opportunities for LZ4 to find matches,

+and `LZ4F_PUBLISH_STATIC_FUNCTIONS`.
+
+
+#### Build macros
+
+The following build macro can be selected to adjust source code behavior at compilation time :
+
+- `LZ4_FAST_DEC_LOOP` : this triggers a speed optimized decompression loop, more powerful on modern cpus.
+  This loop works great on `x86`, `x64` and `aarch64` cpus, and is automatically enabled for them.
+  It's also possible to enable or disable it manually, by passing `LZ4_FAST_DEC_LOOP=1` or `0` to the preprocessor.
+  For example, with `gcc` : `-DLZ4_FAST_DEC_LOOP=1`,
+  and with `make` : `CPPFLAGS+=-DLZ4_FAST_DEC_LOOP=1 make lz4`.
+
+- `LZ4_DISTANCE_MAX` : control the maximum offset that the compressor will allow.
+  Set to 65535 by default, which is the maximum value supported by lz4 format.
+  Reducing maximum distance will reduce opportunities for LZ4 to find matches,
   hence will produce a worse compression ratio.
   However, a smaller max distance can allow compatibility with specific decoders using limited memory budget.
-  This build macro only influences the compressed output of the compressor. 
- 
-- `LZ4_DISABLE_DEPRECATE_WARNINGS` : invoking a deprecated function will make the compiler generate a warning. 
-  This is meant to invite users to update their source code. 
-  Should this be a problem, it's generally possible to make the compiler ignore these warnings, 
-  for example with `-Wno-deprecated-declarations` on `gcc`, 
-  or `_CRT_SECURE_NO_WARNINGS` for Visual Studio. 
-  This build macro offers another project-specific method 
-  by defining `LZ4_DISABLE_DEPRECATE_WARNINGS` before including the LZ4 header files. 
- 
-- `LZ4_USER_MEMORY_FUNCTIONS` : replace calls to <stdlib>'s `malloc`, `calloc` and `free` 
-  by user-defined functions, which must be called `LZ4_malloc()`, `LZ4_calloc()` and `LZ4_free()`. 
-  User functions must be available at link time. 
- 
-- `LZ4_FORCE_SW_BITCOUNT` : by default, the compression algorithm tries to determine lengths 
-  by using bitcount instructions, generally implemented as fast single instructions in many cpus. 
-  In case the target cpus doesn't support it, or compiler intrinsic doesn't work, or feature bad performance, 
-  it's possible to use an optimized software path instead. 
-  This is achieved by setting this build macros . 
-  In most cases, it's not expected to be necessary, 
-  but it can be legitimately considered for less common platforms. 
- 
-- `LZ4_ALIGN_TEST` : alignment test ensures that the memory area 
-  passed as argument to become a compression state is suitably aligned. 
-  This test can be disabled if it proves flaky, by setting this value to 0. 
- 
- 
-#### Amalgamation 
- 
-lz4 source code can be amalgamated into a single file. 
-One can combine all source code into `lz4_all.c` by using following command:

+
+
+#### Amalgamation
+
+lz4 source code can be amalgamated into a single file.
+One can combine all source code into `lz4_all.c` by using following command:
+```
 cat lz4.c lz4hc.c lz4frame.c > lz4_all.c
-``` 
-(`cat` file order is important) then compile `lz4_all.c`. 
-All `*.h` files present in `/lib` remain necessary to compile `lz4_all.c`. 
- 
- 
-#### Windows : using MinGW+MSYS to create DLL 
- 
-DLL can be created using MinGW+MSYS with the `make liblz4` command. 
-This command creates `dll\liblz4.dll` and the import library `dll\liblz4.lib`. 
-To override the `dlltool` command  when cross-compiling on Linux, just set the `DLLTOOL` variable. Example of cross compilation on Linux with mingw-w64 64 bits: 
-``` 
-make BUILD_STATIC=no CC=x86_64-w64-mingw32-gcc DLLTOOL=x86_64-w64-mingw32-dlltool OS=Windows_NT 
-``` 
-The import library is only required with Visual C++. 
-The header files `lz4.h`, `lz4hc.h`, `lz4frame.h` and the dynamic library 
-`dll\liblz4.dll` are required to compile a project using gcc/MinGW. 
-The dynamic library has to be added to linking options. 
-It means that if a project that uses LZ4 consists of a single `test-dll.c` 
-file it should be linked with `dll\liblz4.dll`. For example: 
-``` 
-    $(CC) $(CFLAGS) -Iinclude/ test-dll.c -o test-dll dll\liblz4.dll 
-``` 
-The compiled executable will require LZ4 DLL which is available at `dll\liblz4.dll`. 
- 
-

-Other files present in the directory are not source code. They are : 
- 
- - `LICENSE` : contains the BSD license text 
- - `Makefile` : `make` script to compile and install lz4 library (static and dynamic) 
- - `liblz4.pc.in` : for `pkg-config` (used in `make install`)

   lz4.h generates and decodes LZ4-compressed blocks (doc/lz4_Block_format.md).
   Decompressing such a compressed block requires additional metadata.
   Exact metadata depends on exact decompression function.
   For the typical case of LZ4_decompress_safe(),
   metadata includes block's compressed size, and maximum bound of decompressed size.
   Each application is free to encode and pass such metadata in whichever way it wants.

   Selecting the compression level can be done with LZ4_resetStreamHC_fast() (starts a new stream)
   or LZ4_setCompressionLevel() (anytime, between blocks in the same stream) (experimental).
   LZ4_resetStreamHC_fast() only works on states which have been properly initialized at least once,
   which is automatically the case when state is created using LZ4_createStreamHC().
- 
+
   After reset, a first "fictional block" can be designated as initial dictionary,
   using LZ4_loadDictHC() (Optional).
