```
server.Server.versionAtLeast(minimum: : string) -> Promise<boolean>
```

Whether this server is at least `minimum`, written the way tmux writes it.

This is how a caller gates on a feature that arrived in a known release
without parsing `#{version}` themselves. A named development build such
as `next-3.9` has not shipped the release it names: it is at least
`3.8`, but not at least `3.9`. An untargeted development build (bare
`master`, or `<tag>-master`) names no release it is heading toward, so
nothing bounds it — it is at least anything.

## Example

```ts
if (await server.versionAtLeast("3.3")) {
  await server.setOption("extended-keys", "on");
}
```
