Invoking `sdiff'
****************

   The `sdiff' command merges two files and interactively outputs the
results.  Its arguments are as follows:

     sdiff -o OUTFILE OPTIONS... FROM-FILE TO-FILE

   This merges FROM-FILE with TO-FILE, with output to OUTFILE.  If
FROM-FILE is a directory and TO-FILE is not, `sdiff' compares the file
in FROM-FILE whose file name is that of TO-FILE, and vice versa.
FROM-FILE and TO-FILE may not both be directories.

   `sdiff' options begin with `-', so normally FROM-FILE and TO-FILE
may not begin with `-'.  However, `--' as an argument by itself treats
the remaining arguments as file names even if they begin with `-'.  You
may not use `-' as an input file.

   An exit status of 0 means no differences were found, 1 means some
differences were found, and 2 means trouble.

   `sdiff' without `-o' (or `--output') produces a side-by-side
difference.  This usage is obsolete; use `diff --side-by-side' instead.
