This rephrases part of it and includes instructions to run the `help`
command (rather than including the `help` output directly). In future,
we may directly include shorter `help` outputs or a separate set of
examples. But for now the `help` output may overshadow the error message
we intend to show the user.
```ucm
@unison/base/main> lib.install blah.blah.blah
Sorry, I couldn’t understand your request. I expected a project or
branch, but saw ”blah.blah.blah”.
Usage:
The `lib.install` command installs a dependency into the `lib` namespace.
`lib.install @unison/base/releases/latest` installs the latest release of `@unison/base`
`lib.install @unison/base/releases/3.0.0` installs version 3.0.0 of `@unison/base`
`lib.install @unison/base/topic` installs the `topic` branch of `@unison/base`
```
