              format LTYPE input lines with LFMT

              These format options provide fine-grained control over the  out-
              put

              of diff, generalizing -D/--ifdef.

       LTYPE is 'old', 'new', or 'unchanged'.
              GTYPE is LTYPE or 'changed'.

              GFMT (only) may contain:

       %<     lines from FILE1

       %>     lines from FILE2

       %=     lines common to FILE1 and FILE2

       %[-][WIDTH][.[PREC]]{doxX}LETTER
              printf-style spec for LETTER

              LETTERs are as follows for new group, lower case for old group:

       F      first line number

       L      last line number

       N      number of lines = L-F+1

       E      F-1

       M      L+1

       %(A=B?T:E)
              if A equals B then T else E

              LFMT (only) may contain:

       %L     contents of line

       %l     contents of line, excluding any trailing newline

       %[-][WIDTH][.[PREC]]{doxX}n
              printf-style spec for input line number

              Both GFMT and LFMT may contain:

       %%     %

       %c'C'  the single character C

       %c'\OOO'
              the character with octal code OOO

       C      the character C (other characters represent themselves)

       -d, --minimal
              try hard to find a smaller set of changes

       --horizon-lines=NUM
              keep NUM lines of the common prefix and suffix

       --speed-large-files
              assume large files and many scattered small changes

       --color[=WHEN]
              colorize  the  output;  WHEN can be 'never', 'always', or 'auto'
              (the default)

       --palette=PALETTE
              the  colors  to  use  when  --color  is  active;  PALETTE  is  a
              colon-separated list of terminfo capabilities

       --help display this help and exit

       -v, --version
              output version information and exit

       FILES are 'FILE1 FILE2' or 'DIR1 DIR2' or 'DIR FILE' or 'FILE DIR'.  If
       --from-file or  --to-file  is  given,  there  are  no  restrictions  on
       FILE(s).   If  a FILE is '-', read standard input.  Exit status is 0 if
       inputs are the same, 1 if different, 2 if trouble.
