;; Because namestrings are used, the results shown in the remaining
;; examples are not necessarily the only possible results. Mappings
;; from namestring representation to pathname representation are
;; dependent both on the file system involved and on the implementation
;; (since there may be several implementations which can manipulate the
;; the same file system, and those implementations are not constrained
;; to agree on all details). Consult the documentation for each
;; implementation for specific information on how namestrings are treated
;; that implementation.
