+.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),
+or
+.BR bzip2 (1).
+All options specified are passed directly to
+.B cmp
+or
+.BR diff .
+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
+.B cmp
+or
+.B diff
+is preserved.
+.PP
+The names
+.B lzcmp
+and
+.B lzdiff
+are provided for backward compatibility with LZMA Utils.
