-/* Support for Courier Style directories
- When this code is complete there will be two types of support, which

- folder structure, a "folder" may have a subfolder called
- "folder.subfolder", which is not natural in the file system in the
- sense that I can not stat for "folder.subfolder" wihtout knowing what
- "subfolder" is. It needs to be guessed. Because of this I need to look
- in the list of folders if there is a folder with a name
- "folder.subfolder", before I can say if the folder is dual or not. One
- can avoid this annoyance if one ignores the problem by declaring that
- every folder is dual. I will however code as the default the more
- complicated idea of scaning the containing directory each time it is
- modified and search for subfolders, and list the entries it found.
