+.RI [ cmp_options "] " file1 " [" file2 ]
+.br
+.B xzdiff
+.RI [ diff_options "] " file1 " [" file2 ]
+.br
+.B lzcmp
+.RI [ cmp_options "] " file1 " [" file2 ]
+.br
+.B lzdiff
+.RI [ diff_options "] " file1 " [" file2 ]
+.SH DESCRIPTION
+.B xzcmp
+and
+.B xzdiff
+invoke
+.BR cmp (1)
+or
+.BR diff (1)
+on files compressed with
+.BR xz (1),
+.BR lzma (1),
+.BR gzip (1),
+.BR bzip2 (1),
+.BR lzop (1),
+or
+.BR zstd (1).
+All options specified are passed directly to
+.BR cmp (1)
+or
+.BR diff (1).
+If only one file is specified, then the files compared are
+.I file1
+(which must have a suffix of a supported compression format) and
+.I file1
+from which the compression format suffix has been stripped.
+If two files are specified,
+then they are uncompressed if necessary and fed to
+.BR cmp (1)
+or
+.BR diff (1).
+The exit status from
+.BR cmp (1)
+or
+.BR diff (1)
+is preserved unless a decompression error occurs; then exit status is 2.
+.PP
+The names
+.B lzcmp
+and
+.B lzdiff
+are provided for backward compatibility with LZMA Utils.
+.SH "SEE ALSO"

+.SH BUGS
+Messages from the
+.BR cmp (1)
+or
+.BR diff (1)
+programs refer to temporary filenames instead of those specified.

+xzless, lzless \- view xz or lzma compressed (text) files
+.SH SYNOPSIS
+.B xzless
+.RI [ file ...]
+.br
+.B lzless
+.RI [ file ...]
+.SH DESCRIPTION
+.B xzless
+is a filter that displays text from compressed files to a terminal.
+It works on files compressed with
+.BR xz (1)
+or
+.BR lzma (1).
+If no
+.I files
+are given,
+.B xzless
+reads from standard input.
+.PP
+.B xzless
+uses
+.BR less (1)
+to present its output.
+Unlike
+.BR xzmore ,
+its choice of pager cannot be altered by
+setting an environment variable.
+Commands are based on both
+.BR more (1)
+and
+.BR vi (1)
+and allow back and forth movement and searching.
+See the
+.BR less (1)
+manual for more information.
+.PP
+The command named
+.B lzless
+is provided for backward compatibility with LZMA Utils.
+.SH ENVIRONMENT
+.TP
+.B LESSMETACHARS
+A list of characters special to the shell.
+Set by
+.B xzless
+unless it is already set in the environment.
+.TP
+.B LESSOPEN
+Set to a command line to invoke the
