I packaged a theme and it installs without problems in its own folder, ok thats done. But i want To know for ex. I modify some file in the base folder, but when i uninstall (the theme) i want that the base folder go back to previous state, i mean that if any file was edited or deleted in the deb installing process when uninstall restore all that.
How can i tell meego that remember that when someone uninstall restore those files previous state?
