In the hopes of doing a good job at teaching people what Turso can do,
I am adding built-in manual pages. When the CLI starts, it picks a
feature at random, and tells the user that the feature exists:
```
Turso v0.2.0-pre.8
Enter ".help" for usage hints.
Did you know that Turso supports Change Data Capture? Type .manual cdc to learn more.
This software is ALPHA, only use for development, testing, and experimentation.
Connected to a transient in-memory database.
Use ".open FILENAME" to reopen on a persistent database
```
There is a lot we can do to make this feature world class:
- we can automatically compile examples during compile time like
rust-doc, to make sure examples used in the manuals always work
- we can implement scrolling and navigation
- we can document a lot more features
But for now, this is a start!
