It seems to work quite well.  I tried the program on a non-trivial pkg tree
(only to-be-updated packages are shown in the graph), and the resulting
script looks fine (correct build order).

But it doesn't have any error handling.  If e.g. kdelibs fails, it prints
out an error but just continues (needlessly) rebuilding all kde* packages.  

There's room for improvement, but it looks good.
