-c       Produce a difference list with 3 lines of context.  -c
         modifies the output format slightly: the output begins
         with identification of the files involved, followed by
         their creation dates, then each change separated by a
         line containing about twelve asterisks (*)s.  Lines
         removed from file1 are marked with -, and lines added to
         file2 are marked +.  Lines that change from one file to
         the other are marked in both files with with !.  Changes
         that lie within 3 lines of each other in the file are
         grouped together on output.

-C n     Output format similar to -c but with n lines of context.
