Stateless enumerators for local subdirectories.
2. Commands
Dir [n: number]
Lists the subdirectories on the local disk that have at most n components.
(n defaults to infinity)
SubDir [n: integer]
Lists the subdirectories on the local disk relative to the current working directory.
n is the number of subdirectory components allowed in addition to the those of the current working directory.
If n is negative, does an "uplevel" list.
