13 - `lz4` : default CLI, with a command line syntax close to gzip
14 - `lz4c` : Same as `lz4` with additional support legacy lz4 commands (incompatible with gzip)
15 - `lz4c32` : Same as `lz4c`, but forced to compile in 32-bits mode
17 The CLI generates and decodes [LZ4-compressed frames](../doc/lz4_Frame_format.md).
21 CLI supports aggregation of parameters i.e. `-b1`, `-e18`, and `-i1` can be joined into `-b1e18i1`.
25 CLI includes in-memory compression benchmark module for lz4.
31 One can select compression levels starting from `-b` and ending with `-e`.
32 The `-i` parameter selects a number of seconds used for each of tested levels.
37 The full list of commands can be obtained with `-h` or `-H` parameter:
