-I, --ignore pattern don't process files matching pattern
-r, --rcs ignore differences in RCS strings
-t, --bktag ignore differences in Bitkeeper strings
-c, --context num set number of lines of context to show
-b, -w, -B, -i, -d pass these on to diff(1)
-S show files that are the same in the file list

Dirdiff compares all the files in up to five directories. There is one \
column in the main window for each directory.
Each file is shown with a coloured square indicating its status. 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.
Double-click a file to show differences between two versions. By default, \
the first and last versions are compared, but this can be changed by the \
'Diff' menu in the main window.
You can select several files to copy or to make a patch by shift-clicking.
You can search for a file by typing part of its name in the entry and \
pressing the <Return> key.
In the diff window, check the boxes on the left margin for changes you \
want to preserve, and then choose 'Merge' to move those changes into one \
of the files. Alternatively, choose 'Copy' in the main window to copy \
across the whole file, replacing any changes.
'Make patch' 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(1) 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.
