The man pages of lzmainfo, xzmore, and xzdec had similar
constructs as the man page of xz had before the commit
eb6ca9854b. Eric S. Raymond
didn't mention these man pages in his bug report, but
it's nice to be consistent.

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

.B 0
|
|
All is good.
|
|
.TP
|
|
.B 1
|
|
An error occurred.
|
|
.SH BUGS
|
|
.B lzmainfo
|
|
uses
|
|
.B MB
|
|
while the correct suffix would be
|
|
.B MiB
|
|
(2^20 bytes).
|
|
This is to keep the output compatible with LZMA Utils.
