pub const LINK_TYPES: &str = "\
List the kinds of link, and what a write takes for each.
```
ytcli link types
```
There are **two** vocabularies here and they are not the same list. `WRITE` is
what `ytcli issue link add` takes — a directional phrase like `depends on`.
`TYPE` is the id Tracker files the link under and answers reads with — `depends`.
Writing the type id is refused, and this tool's own help got that wrong for
several releases, so the two are printed side by side rather than separately.
`MEANS` is Tracker's own wording for that direction, in the organisation's
language, and it describes the end you are on.
A direction with no write name — `cloners` — is printed with a dash rather than
left out. Links of that type come back from reads, and no relationship in the
write vocabulary makes one; dropping the row would say the type does not exist.";
