pub const WIKI_UPLOAD: &str = "\
Attach files to a Yandex Wiki page.
```
ytcli wiki upload users/ilubenets/runbook rollback.pdf
ytcli wiki upload users/ilubenets/runbook diagram.png notes.txt
```
Each file goes through the Wiki's upload session: opened, sent in 8 MB parts,
finished, then attached. Progress shows on stderr when there is a terminal. If
anything fails part way, the session is aborted so it does not keep holding
the account's upload quota. Files already attached stay attached, and each
gets its own line with the new attachment's id.
Every file is read before anything is sent, so a missing one stops the
command at the start. The profile and organisation are announced first, and
`--dry-run` sends nothing.";
