pub const WIKI_UPDATE: &str = "\
Replace a Yandex Wiki page's text, or retitle it.
```
ytcli wiki update users/ilubenets/notes --from notes.md
ytcli wiki update users/ilubenets/notes --title \"Old notes\"
ytcli wiki update users/ilubenets/notes --from - --merge < notes.md
```
`--from` replaces the whole text; `wiki append` adds to it instead. If someone
else edited the page since, the Wiki refuses, unless `--merge` asks it to fold
their edits in. Announced first; `--dry-run` sends nothing, not even the
lookup of the page.";
