If only one of the images is filed in and its packages have dependencies on the other, those dependencies are no longer satisfied. The graph will not be drawn until the image is stable again. Once the other image is loaded or the dependencies are removed, the image will become stable again and the graph will be drawn. Packages Packages must have unique names across all images. Packages have the same adding, removing, filing out, loading functionality as images.
Packages have different settings though.
Identifying classes allow for checks to be made on the current system dictoionary to determine whether or not a package's files need to be filed in. They also are used to determine whether or not conflicting packages are currently in the system. Files Files can be simply added or deleted. The only requirement is that the file exists. Dependencies Dependencies can be added and removed.
