25 | ;;; Commentary: | |
26 | ||
27 | ;; This is preliminary support for Subversion (http://subversion.tigris.org/). | |
28 | ;; It started as `sed s/cvs/svn/ vc.cvs.el' (from version 1.56) | |
29 | ;; and hasn't been completely fixed since. | |
30 | ||
31 | ;; Sync'd with Subversion's vc-svn.el as of revision 5801. | |
32 | ||
33 | ;;; Bugs: | |
34 | ||
fd140743 | 35 | ;; - VC-dired is (really) slow. |
