13
14       Mandatory  arguments  to  long  options are mandatory for short options
15       too.

18              output all changes, bracketing conflicts

20       -e, --ed
21              output ed script incorporating changes from OLDFILE to  YOURFILE
22              into MYFILE
23
24       -E, --show-overlap
25              like -e, but bracket conflicts
26
27       -3, --easy-only
28              like -e, but incorporate only nonoverlapping changes
29
30       -x, --overlap-only
31              like -e, but incorporate only overlapping changes
32
33       -X     like -x, but bracket conflicts
34
35       -i     append 'w' and 'q' commands to ed scripts
36
37       -m, --merge
38              output  actual  merged file, according to -A if no other options
39              are given
40
41       -a, --text
42              treat all files as text
43
44       --strip-trailing-cr
45              strip trailing carriage return on input
46
47       -T, --initial-tab
48              make tabs line up by prepending a tab
49
50       --diff-program=PROGRAM
51              use PROGRAM to compare files
52
53       -L, --label=LABEL
54              use LABEL instead of file name (can  be  repeated  up  to  three
55              times)
56
57       --help display this help and exit
58
59       -v, --version
60              output version information and exit
61
62       The  default  output format is a somewhat human-readable representation
63       of the changes.
64
65       The -e, -E, -x, -X (and corresponding long) options cause an ed  script
66       to be output instead of the default.
67
68       Finally,  the  -m  (--merge) option causes diff3 to do the merge inter‐
69       nally and output the actual merged file.  For unusual  input,  this  is
70       more robust than using ed.
71
72       If a FILE is '-', read standard input.  Exit status is 0 if successful,
73       1 if conflicts, 2 if trouble.
