     Name
          diff3 - Compares three files.

     Syntax
          diff3 [ -ex3 ] file1 file2 file3

     Description
          diff3 compares three versions of a file, and publishes
          disagreeing ranges of text flagged with these codes:

               ====            All three files differ

               ====1           File1 is different

               ====2           File2 is different

               ====3           File3 is different

          The type of change suffered in converting a given range of a
          given file to some other range is indicated in one of these
          ways:

               f : n1 a        Text is to be appended after line
                               number n1 in file f, where f = 1, 2, or
                               3.

               f : n1 , n2 c   Text is to be changed in the range line
                               n1 to line n2.  If n1 = n2, the range
                               may be abbreviated to n1.

          The original contents of the range follows immediately after
          a c indication.  When the contents of two files are
          identical, the contents of the lower-numbered file is
          suppressed.

          Under the -e option, diff3 publishes a script for the editor
          ed that will incorporate into file1 all changes between
          file2 and file3, i.e., the changes that normally would be
          flagged ==== and ====3.  The -x option produces a script to
          incorporate changes flagged with ``====''.  Similarly, the
          -3 option produces a script to incorporate changes flagged
          with ``====3''.  The following command applies a resulting
          editing script to file1:

               (cat script; echo '1,$p') | ed - file1
