;;; Credits:
;; Designed and implemented by Eric S. Raymond, originally as part of VC mode.
+;; Stefan Monnier and Dan Nicolaescu contributed substantial work on the
+;; vc-dir front end.
;;; Commentary:
;; of the file tree from the state of the currently visited buffer
;; and returns that subset, presumably to a client mode.
;;
-;; The user may be attempting to select one of three contexts: an
-;; explicitly selected fileset, the current working directory, or a
-;; global (null) context. The user may be looking at either of two
-;; different views; a buffer visiting a file, or a directory buffer
-;; generated by vc-dispatcher. The main UI problem connected with
-;; this mode is that the user may need to be able to select any of
-;; these three contexts from either view.
+;; The user may be looking at either of two different views; a buffer
+;; visiting a file, or a directory buffer generated by vc-dispatcher.
;;
;; The lower layer of this mode runs commands in subprocesses, either
;; synchronously or asynchronously. Commands may be launched in one
;; about the semantics of individual states, but mark and unmark commands
;; treat all entries with the same state as the currently selected one as
;; a unit.
-
+
+;; The interface:
+;;
+;; The main interface to the lower level is vc-do-command. This launches a
+;; comand, synchronously or asynchronously, making the output available
+;; in a command log buffer. Two other functions, (vc-start-annotation) and
+;; (vc-finish-logentry), allow you to associate a command closure with an
+;; abbotation buffer so that when the user confirms the comment the closure
+;; is run (with the comment as part of its context).
+;;
+;; The interface to the upper level has the two main entry points (vc-dir)
+;; and (vc-dispatcher-selection-set) and a couple of convenience functions.
+;; (vc-dir) sets up a dispatcher browsing buffer; (vc-dispatcher-selection-set)
+;; returns a selection set of files, either the marked files in a browsing
+;; buffer or the singleton set consisting of the file visited by the current
+;; buffer (when that is appropriate). It also does what is needed to ensure
+;; that on-disk files and the contents of their visiting Emacs buffers
+;; coincide.
+;;
+;; When the client mode adds a local mode-line-hook to a buffer, it
+;; will be called with the buffer file name as argument whenever the
+;; dispatcher resynchs the buffer.
+
;; To do:
;;
;; - vc-dir-kill-dir-status-process should not be specific to dir-status,
-;; it should work for other async commands as well (pull/push/...).
+;; it should work for other async commands done through vc-do-command
+;; as well,
;;
-;; - the *VC-log* buffer needs font-locking.
-;;
-;; - Set `vc-dir-insert-directories' to t and check what operations
-;; and backends do not support directory arguments and fix them.
+;; - log buffers need font-locking.
;;
;; - vc-dir needs mouse bindings.
;;
-;; - vc-dir needs more key bindings for VC actions.
-;;
;; - vc-dir toolbar needs more icons.
;;
-;; - vc-dir-next-line should not print an "end of buffer" message when
-;; invoked with the cursor on the last file.
-;;
-;; - add commands to move to the prev/next directory in vc-dir.
-;;
-;; - document vc-dir in the manual.
+;; - vc-dir-menu-map-filter hook call needs to be moved to vc.el.
