jpayne@68: .SH DESCRIPTION
jpayne@68: .B lzmainfo
jpayne@68: shows information stored in the
jpayne@68: .B .lzma
jpayne@68: file header.
jpayne@68: It reads the first 13 bytes from the specified
jpayne@68: .IR file ,
jpayne@68: decodes the header, and prints it to standard output in human
jpayne@68: readable format.
jpayne@68: If no
jpayne@68: .I files
jpayne@68: are given or
jpayne@68: .I file
jpayne@68: is
jpayne@68: .BR \- ,
jpayne@68: standard input is read.
jpayne@68: .PP
jpayne@68: Usually the most interesting information is
jpayne@68: the uncompressed size and the dictionary size.
jpayne@68: Uncompressed size can be shown only if
jpayne@68: the file is in the non-streamed
jpayne@68: .B .lzma
jpayne@68: format variant.
jpayne@68: The amount of memory required to decompress the file is
jpayne@68: a few dozen kilobytes plus the dictionary size.
jpayne@68: .PP
jpayne@68: .B lzmainfo
jpayne@68: is included in XZ Utils primarily for
jpayne@68: backward compatibility with LZMA Utils.

jpayne@68: .SH BUGS
jpayne@68: .B lzmainfo
jpayne@68: uses
jpayne@68: .B MB
jpayne@68: while the correct suffix would be
jpayne@68: .B MiB
jpayne@68: (2^20 bytes).
jpayne@68: This is to keep the output compatible with LZMA Utils.
