25;;; local-definitions-in root name
26;;; Returns a list of names defined locally in the named
27;;; subdirectory of root.
28;;; definitions-in root name
29;;; Returns a list of all names defined in the named
30;;; subdirectory of root. The list includes alll locally
31;;; defined names as well as all names inherited from a
32;;; member of a use-list.
33;;;
34;;; A convenient interface for examining the nature of things:
35;;;
36;;; ls . various-names
37;;;
38;;; With just one argument, interpret that argument as the
39;;; name of a subdirectory of the current module and
40;;; return a list of names defined there.
41;;;
42;;; With more than one argument, still compute
43;;; subdirectory lists, but return a list:
44;;; ((<subdir-name> . <names-defined-there>)
45;;; (<subdir-name> . <names-defined-there>)
46;;; ...)
