 .SH DESCRIPTION
-Zdiff \- Diff/cmp wrapper for compressed files.
+Zdiff compares two files ("\-" means standard input), and if they
+differ, shows the differences line by line. If any given file is
+compressed, its uncompressed content is used. Zdiff is a front end to
+the diff program and has the limitation that messages from diff refer to
+temporary filenames instead of those specified.
+The supported compressors are bzip2, gzip, lzip and xz.
 .PP
-Zdiff is a wrapper script around the diff and cmp commands that allows
-transparent comparison of any combination of compressed and
-non\-compressed files. If any given file is compressed, its uncompressed
-content is used. The supported compressors are bzip2, gzip, lzip and xz.
+Compares <file1> to <file2>. If <file2> is omitted zdiff tries the
+following:
+If <file1> is compressed, compares <file1> to the file with the
+corresponding decompressed file name (removes the extension from
+<file1>).
+If <file1> is not compressed, compares <file1> to the uncompressed
+contents of <file1>.[bz2|gz|lz|xz] (the first one that is found).
+If no suitable file is found, compares <file1> to data read from
+standard input.
 .PP
-Zcmp is a shortcut for "zdiff \fB\-\-cmp\fR"
-.PP
-Compares FILE1 to FILE2. If FILE2 is omitted and FILE1 is compressed,
-compares FILE1 to the file with the corresponding decompressed file
-name (removes the extension from FILE1). If FILE2 is omitted and FILE1
-is not compressed, compares FILE1 to the uncompressed contents of
-FILE1.[bz2|gz|lz|xz] (the first one that is found).
-DIFF_OPTIONS are passed directly to diff or cmp.
-The exit status from diff or cmp is preserved.
+Exit status is 0 if inputs are identical, 1 if different, 2 if trouble.
