| 142 | `list-diary-entries-hook' adds or manipulates diary entries from |

| 144 | from other files or to sort the diary entries. Invoked *once* only, |
| 145 | before the display hook is run. |
| 146 | |
| 147 | `diary-display-hook' does the actual display of information. If this is |
| 148 | nil, simple-diary-display will be used. Use add-hook to set this to |
| 149 | fancy-diary-display, if desired. If you want no diary display, use |
| 150 | add-hook to set this to ignore. |
