+.SH NAME
+xzdec, lzmadec \- Small .xz and .lzma decompressors
+.SH SYNOPSIS
+.B xzdec
+.RI [ option ]...
+.RI [ file ]...
+.br
+.B lzmadec
+.RI [ option ]...
+.RI [ file ]...
+.SH DESCRIPTION
+.B xzdec
+is a liblzma-based decompression-only tool for
+.B .xz
+(and only
+.BR .xz )
+files.
+.B xzdec
+is intended to work as a drop-in replacement for
+.BR xz (1)
+in the most common situations where a script has been written to use
+.B "xz \-\-decompress \-\-stdout"
+(and possibly a few other commonly used options) to decompress
+.B .xz
+files.
+.B lzmadec
+is identical to
+.B xzdec
+except that
+.B lzmadec
+supports
+.B .lzma
+files instead of
+.B .xz
+files.
+.PP
+To reduce the size of the executable,
+.B xzdec
+doesn't support multithreading or localization, and doesn't read options from
+.B XZ_OPT
+environment variable.
+.B xzdec
+doesn't support displaying intermediate progress information: sending
+.B SIGINFO
+to
+.B xzdec
+does nothing, but sending
+.B SIGUSR1
+terminates the process instead of displaying progress information.
+.SH OPTIONS
+.TP
+.BR \-d ", " \-\-decompress ", " \-\-uncompress
+Ignored for
+.BR xz (1)
+compatibility.
+.B xzdec
+supports only decompression.
+.TP
+.BR \-k ", " \-\-keep
+Ignored for
+.BR xz (1)
+compatibility.
+.B xzdec
+never creates or removes any files.
+.TP
+.BR \-f ", " \-\-force
+Ignored for
+.BR xz (1)
+compatibility.
+.TP
+.BR \-c ", " \-\-stdout ", " \-\-to-stdout
+Ignored for
+.BR xz (1)
+compatibility.
+.B xzdec
+always writes the decompressed data to standard output.
+.TP
+\fB\-M\fR \fIlimit\fR, \fB\-\-memory=\fIlimit
+Set the memory usage
+.IR limit .
+If this option is specified multiple times, the last one takes effect. The
+.I limit
+can be specified in multiple ways:
+.RS
+.IP \(bu 3
+The
+.I limit
+can be an absolute value in bytes. Using an integer suffix like
+.B MiB
+can be useful. Example:
+.B "\-\-memory=80MiB"
+.IP \(bu 3
+The
+.I limit
+can be specified as a percentage of physical RAM. Example:
+.B "\-\-memory=70%"
+.IP \(bu 3
+The
+.I limit
+can be reset back to its default value (currently 40 % of physical RAM)
+by setting it to
+.BR 0 .
+.IP \(bu 3
+The memory usage limiting can be effectively disabled by setting
+.I limit
+to
+.BR max .
+This isn't recommended. It's usually better to use, for example,
+.BR \-\-memory=90% .
+.RE
+.IP
+The current
+.I limit
+can be seen near the bottom of the output of the
+.B \-\-help
+option.
+.TP
+.BR \-q ", " \-\-quiet
+Specifying this once does nothing since
+.B xzdec
+never displays any warnings or notices.
+Specify this twice to suppress errors.
+.TP
+.BR \-Q ", " \-\-no-warn
+Ignored for
+.BR xz (1)
+compatibility.
+.B xzdec
+never uses the exit status
+.BR "2" .
+.TP
+.BR \-h ", " \-\-help
+Display a help message and exit successfully.
+.TP
+.BR \-V ", " \-\-version
+Display the version number of
+.B xzdec
+and liblzma.
+.SH "EXIT STATUS"
+.TP
+.B 0
+All was good.
+.TP
+.B 1
+An error occurred.
+.PP
+.B xzdec
+doesn't have any warning messages like
+.BR xz (1)
+has, thus the exit status
+.B 2
+is not used by
+.BR xzdec .
+.SH NOTES
+.B xzdec
+and
+.B lzmadec
+are not really that small. The size can be reduced further by dropping
+features from liblzma at compile time, but that shouldn't usually be done
+for executables distributed in typical non-embedded operating system
+distributions. If you need a truly small
+.B .xz
+decompressor, consider using XZ Embedded.
+.\" TODO: Provide URL to XZ Embedded.
