+NAME
+       xzdec, lzmadec - Small .xz and .lzma decompressors
+
+SYNOPSIS
+       xzdec [option...]  [file...]
+       lzmadec [option...]  [file...]
+
+DESCRIPTION
+       xzdec is a liblzma-based decompression-only tool for .xz (and only .xz)
+       files.  xzdec is intended to work as a drop-in replacement for xz(1) in
+       the  most  common  situations where a script has been written to use xz
+       --decompress --stdout (and possibly a few other commonly used  options)
+       to  decompress  .xz  files.   lzmadec is identical to xzdec except that
+       lzmadec supports .lzma files instead of .xz files.
+
+       To reduce the size of the  executable,  xzdec  doesn't  support  multi-
+       threading  or  localization,  and doesn't read options from XZ_DEFAULTS
+       and XZ_OPT environment variables.   xzdec  doesn't  support  displaying
+       intermediate  progress information: sending SIGINFO to xzdec does noth-
+       ing, but sending SIGUSR1 terminates the process instead  of  displaying
+       progress information.
+
+OPTIONS
+       -d, --decompress, --uncompress
+              Ignored for xz(1) compatibility.  xzdec supports only decompres-
+              sion.
+
+       -k, --keep
+              Ignored for xz(1) compatibility.  xzdec never creates or removes
+              any files.
+
+       -c, --stdout, --to-stdout
+              Ignored for xz(1) compatibility.  xzdec always writes the decom-
+              pressed data to standard output.
+
+       -q, --quiet
+              Specifying this once does nothing since xzdec never displays any
+              warnings or notices.  Specify this twice to suppress errors.
+
+       -Q, --no-warn
+              Ignored for xz(1) compatibility.  xzdec never uses the exit sta-
+              tus 2.
+
+       -h, --help
+              Display a help message and exit successfully.
+
+       -V, --version
+              Display the version number of xzdec and liblzma.
+
+EXIT STATUS
+       0      All was good.
+
+       1      An error occurred.
+
+       xzdec doesn't have any warning messages like xz(1) has, thus  the  exit
+       status 2 is not used by xzdec.
+
+NOTES
+       Use  xz(1)  instead of xzdec or lzmadec for normal everyday use.  xzdec
+       or lzmadec are meant only for situations where it is important to  have
+       a smaller decompressor than the full-featured xz(1).
+
+       xzdec  and  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 .xz
+       decompressor, consider using XZ Embedded.
