;;; Commentary:
;;
;; This is an interface for managing Subversion working copies. It
;; can show you an up-to-date view of the current status, and commit
;; changes. If also helps you do other tasks such as updating,
;; switching, diffing and more.
;;
;; To get you started, add this line to your startup file:
;;
;; (autoload 'svn-status "dsvn" "Run `svn status'." t)
;; (autoload 'svn-update "dsvn" "Run `svn update'." t)
;;
;; This file integrates well with vc-svn, so you might want to do this
;; as well:
;;
;; (require 'vc-svn)
;;
;; To get the status view, type
;;
;; M-x svn-status
;;
;; and select a directory where you have a checked-out Subversion
;; working copy. A buffer will be created that shows what files you
;; have modified, and any unknown files. The file list corresponds
;; closely to that produced by "svn status", only slightly
;; reformatted.
;;
;; Navigate through the file list using "n" and "p", for next and
;; previous file, respectively.
;;
;; You can get a summary of available commands by typing "?".
;;
;; Some commands operate on files, and can either operate on the file
;; under point, or on a group of files that have been marked. The
;; commands used for marking a file are the following:
;;
;; m mark and go down
;; DEL unmark and go up
;; u unmark and go down
;; SPC toggle mark
;; M-DEL unmark all
;;
;; The commands that operate on files are:
;;
;; f Visit the file under point (does not use marks)
;; o Visit the file under point in another window (does not use marks)
;; = Show diff of uncommitted changes. This does not use marks
;; unless you give a prefix argument (C-u)
;; c Commit files
;; a Add files
;; r Remove files
;; R Resolve conflicts
;; M Rename/move files
;; U Revert files
;; P View or edit properties of the file or directory under point
;; (does not use marks)
;; l Show log of file or directory under point (does not use marks)
;;
;; These commands update what is shown in the status buffer:
;;
;; g Rerun "svn status" to update the list. Use a prefix
;; argument (C-u) to clear the list first to make sure that
;; it is correct.
;; s Update status of selected files
;; S Show status of specific file or directory
;; x Expunge unchanged files from the list
;;
;; To update the working copy:
;;
;; M-u Run "svn update". If a prefix argument is given (C-u),
;; you will be prompted for a revision to update to.
;; M-s Switch working copy to another branch.
;; M-m Merge in changes using "svn merge".
;;
;; To view the Subversion log, type "M-x svn-log".
;;
;; Bugs and missing features:
;;
;; - Annotate (blame).
;; - Log, with a useful log mode where the user can easily view any revision
;; as a diff or visit a revision of a file in a buffer.
;; - Integration with ediff or similar to resolve conflicts.
