lzmainfo - show infomation stored in the .lzma file header
lzmainfo [--help] [--version] [file]...
lzmainfo shows information stored in the .lzma file header. It reads
the first 13 bytes from the specified file, decodes the header, and
prints it to standard output in human readable format. If no files are
given or file is -, standard input is read.
Usually the most interesting information is the uncompressed size and
the dictionary size. Uncompressed size can be shown only if the file is
in the non-streamed .lzma format variant. The amount of memory required
to decompress the file is a few dozen kilobytes plus the dictionary
lzmainfo is included in XZ Utils primarily for backward compatibility
with LZMA Utils.

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