+"""Bintool implementation for lz4
+
+lz4 allows compression and decompression of files.
+
+Documentation is available via::
+
+   man lz4
+
+Here is the help:
+
+*** LZ4 command line interface 64-bits v1.9.3, by Yann Collet ***
+Usage :
+      lz4 [arg] [input] [output]
+
+input   : a filename
+          with no FILE, or when FILE is - or stdin, read standard input
+Arguments :
+ -1     : Fast compression (default)
+ -9     : High compression
+ -d     : decompression (default for .lz4 extension)
+ -z     : force compression
+ -D FILE: use FILE as dictionary
+ -f     : overwrite output without prompting
+ -k     : preserve source files(s)  (default)
+--rm    : remove source file(s) after successful de/compression
+ -h/-H  : display help/long help and exit
+
+Advanced arguments :
+ -V     : display Version number and exit
+ -v     : verbose mode
+ -q     : suppress warnings; specify twice to suppress errors too
+ -c     : force write to standard output, even if it is the console
+ -t     : test compressed file integrity
+ -m     : multiple input files (implies automatic output filenames)
+ -r     : operate recursively on directories (sets also -m)
+ -l     : compress using Legacy format (Linux kernel compression)
+ -B#    : cut file into blocks of size # bytes [32+]
+                     or predefined block size [4-7] (default: 7)
+ -BI    : Block Independence (default)
+ -BD    : Block dependency (improves compression ratio)
+ -BX    : enable block checksum (default:disabled)
+--no-frame-crc : disable stream checksum (default:enabled)
+--content-size : compressed frame includes original size (default:not present)
+--list FILE : lists information about .lz4 files (useful for files compressed
+    with --content-size flag)
+--[no-]sparse  : sparse mode (default:enabled on file, disabled on stdout)
+--favor-decSpeed: compressed files decompress faster, but are less compressed
+--fast[=#]: switch to ultra fast compression level (default: 1)
+--best  : same as -12
+Benchmark arguments :
+ -b#    : benchmark file(s), using # compression level (default : 1)
+ -e#    : test all compression levels from -bX to # (default : 1)
+ -i#    : minimum evaluation time in seconds (default : 3s)
