The script does the following: All .cpp and .h files in the current directory and subdirectories are checked to see which include statements could be omitted without causing a build error. Many of these omissions would not be desired. For example, currently if you don't include Undo.h in Undo.cpp, there is no error because Undo.h is included in Cursor.h which is included in Undo.cpp. But clearly we do want to include Undo.h in Undo.cpp. See #6305.
