+
+;;; Commentary:
+
+;; This is preliminary support for Subversion (http://subversion.tigris.org/).
+;; It started as `sed s/cvs/svn/ vc.cvs.el' (from version 1.56)
+;; and hasn't been completely fixed since.
+
+;; Sync'd with Subversion's vc-svn.el as of revision 5801.
+
+;;; Bugs:
+
+;; - VC-dired is either not working or (really) dog slow.
+;; - vc-print-log does not always jump to the proper log entry because
+;; it tries to jump to version 1234 even if there's only an entry
+;; for 1232 (because the file hasn't changed since).
