12 lzmainfo shows information stored in the .lzma file header. It reads
13 the first 13 bytes from the specified file, decodes the header, and
14 prints it to standard output in human readable format. If no files are
15 given or file is -, standard input is read.
16
17 Usually the most interesting information is the uncompressed size and
18 the dictionary size. Uncompressed size can be shown only if the file
19 is in the non-streamed .lzma format variant. The amount of memory
20 required to decompress the file is a few dozen kilobytes plus the dic‐
21 tionary size.

23 lzmainfo is included in XZ Utils primarily for backward compatibility
24 with LZMA Utils.

32 lzmainfo uses MB while the correct suffix would be MiB (2^20 bytes).
33 This is to keep the output compatible with LZMA Utils.
