;; 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:
;; to address that involves selecting sets of files, or possibly
;; directories, and passing the selection set to slave commands. The
;; prototypical example, from which this code is derived, is talking
-;; to version-control systems.
+;; to version-control systems.
;;
;; vc-dispatcher.el is written to decouple the UI issues in such front
-;; ends from their application-specific logic. It also provides a
+;; ends from their application-specific logic. It also provides a
;; service layer for running the slave commands either synchronously
;; or asynchronously and managing the message/error logs from the
;; command runs.
;; Dispatcher's universe:
;;
;; The universe consists of the file tree rooted at the current
-;; directory. The dispatcher's upper layer deduces some subset
-;; of the file tree from the state of the currently visited buffer
+;; directory. The dispatcher's upper layer deduces some subset
+;; 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
;; of two ways: they may be run immediately, or the calling mode can
;; create a closure associated with a text-entry buffer, to be
-;; executed when the user types C-c to ship the buffer contents. In
+;; executed when the user types C-c to ship the buffer contents. In
;; either case the command messages and error (if any) will remain
;; available in a status buffer.
-(provide 'vc-dispatcher)
+;; Special behavior of dispatcher directory buffers:
+;;
+;; In dispatcher directory buffers, facilities to perform basic
+;; navigation and selection operations are provided by keymap and menu
+;; entries that dispatcher sets up itself, so they'll be uniform
+;; across all dispatcher-using client modes. Client modes are
+;; expected to append to these to provide mode-specific bindings.
+;;
+;; The standard map associates a 'state' slot (that the client mode
+;; may set) with each directory entry. The dispatcher knows nothing
+;; 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
+;; command, synchronously or asynchronously, making the output available
+;; in a command log buffer. Two other functions, (vc-start-logentry) and
+;; (vc-finish-logentry), allow you to associate a command closure with an
+;; annotation 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 vc-mode-line-hook to a buffer, it
+;; will be called with the buffer file name as argument whenever the
+;; dispatcher resynchs the buffer.
