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 libfilecmp.so.0.0 shared library for the -r or -t
flags to work.
