39 | ;; Load this library to register bzr support in VC. It covers basic VC |

41 | ;; version combinations, namely those current on the authors' PCs. | |

45 | ;; Known bugs | |
46 | ;; ========== | |
47 | ||
48 | ;; When edititing a symlink and *both* the symlink and its target | |
49 | ;; are bzr-versioned, `vc-bzr` presently runs `bzr status` on the | |
50 | ;; symlink, thereby not detecting whether the actual contents | |
51 | ;; (that is, the target contents) are changed. | |
52 | ;; See https://bugs.launchpad.net/vc-bzr/+bug/116607 | |
53 | ||
