       dirdiff  [-a|--all]  [-o|--only  pattern]  [-I|--ignore  pattern]  [-r|--rcs] [-t|--bktag]
       [-c|--context num] [-b] [-w] [-B] [-i] [-d] [-S] [-k] dir1 dir2 ...


              Don't exclude any files.

       -o,--only pattern
              Only process files matching pattern.

       -I,--ignore pattern
              Don't process files matching pattern.

              Ignore differences in Bitkeeper strings.

       -c,--context num
              Set number of lines of context to show.

              Pass these on to diff.

       -K     Enable bitkeeper support.


       Dirdiff is a graphical tool for displaying the differences between directory trees (up  to
       5) and for merging changes from one tree into another.

       At  startup,  dirdiff  displays  a main window with a list of the files that are different
       between the trees.  Colored squares  are  used  to  indicate  the  relative  ages  of  the
       versions.   Files are like leaves on a deciduous tree: the newest ones are green, and then
       they turn yellow, orange, and red as  they  get  older.   Missing  files  are  black,  and
       directories are white.

       To  see the differences between two versions of a file, double-click on the file name.  By
       default, the first and last versions are compared, but this can be changed using the  Diff
       menu  in  the main window.  In the differences window, there are checkboxes to the left of
       all the sections which are different.  You can  use  button  1  to  select  an  individual
       checkbox,  or  shift-button 1 or button 3 to select a whole group.  Selecting a line means
       that you are asking for that change to be made when you update either of the  files  using
       the  Merge  menu.  The line will be removed if it is already present or added if it is not

       To copy from one tree to another, click on the file name and select the  appropriate  copy
       operation from the Copy menu of the main window.

       Selecting  Make patch from the File menu of the main window produces a file describing the
       changes between the files that can be applied by the patch tool.  You can edit  the  patch
       before  saving,  and may wish to add explanatory text, instructions, or patch Prereq lines
       at the beginning.  To save the patch, enter a filename in the patch window relative to the
       current directory, and choose Save.  This will also close the window.

       If  you are sending out patches, then the from directory should be the original version of
       the source.  Try to make sure  that  the  two  files  have  the  same  number  of  leading
       directories.  See the patch(1) man page for more information.


       Dirdiff  needs  to  be  able to load the shared library for the -r or -t
       flags to work.
