| 25 | |
| 26 | ;; This facility is documented in the Emacs Manual. |
| 27 | |
| 28 | ;; Todo: |
| 29 | |
| 30 | ;; - Find/use/create _MTN/log if there's a _MTN directory. |
| 31 | ;; - Find/use/create ++log.* if there's an {arch} directory. |
| 32 | ;; - Use an open *VC-Log* or *cvs-commit* buffer if it's related to the |
| 33 | ;; source file. |
| 34 | ;; - Don't add TAB indents (and username?) if inserting entries in those |
| 35 | ;; special places. |
