In order to create diffs use diff (available on most unix systems).
Put the original tree in lets say orig and the modified one in new.
run diff on the complete set like this:
diff -u -r orig new > orig-new.diff
(the -u is for unified diff format (i.e. + is printed for added/replaced
lines and - is for deleted lines along with some context), while
-r is for recursive directory comparison and diffing.))
Please be aware that diff is not well suited for binary files.
(unless you use -a it will ignore the binary files altogether)
Hope that helps a bit,
(PS: Files are diffable unless there are binary images included)
