Tell me about the Racket "Scribble" typesetting system.

Scribble is a typesetting system and programming language designed for creating documents and software documentation. It is a part of the Racket programming language ecosystem, which is a general-purpose, multi-paradigm programming language in the Lisp/Scheme family. Scribble is built on top of Racket, which means that you can use Racket's powerful features and libraries when creating your documents.

Scribble is designed to be expressive and flexible, allowing you to mix prose and code seamlessly. It's particularly well-suited for creating technical documentation that includes executable code examples, mathematical formulas, or other complex elements.

Here are some key features of Scribble:

1. Extensible: Scribble is built on Racket, which makes it highly customizable and extensible. Users can define their own document structures, create new markup languages, and use macros to build reusable components.

2. Programmable: As Scribble is a part of the Racket ecosystem, you can write Racket code directly within your documents. This is useful for automating parts of the document creation process, generating content, or incorporating live code examples.

3. Support for multiple output formats: Scribble can generate output in various formats, such as HTML, PDF, and LaTeX. This makes it versatile for different use cases, from web documentation to print-ready publications.

4. Syntax: Scribble uses a lightweight syntax that is easy to read and write. It borrows some elements from Markdown, making it familiar to users of other lightweight markup languages.

5. Embedded documentation: With Scribble, you can write documentation directly alongside your Racket code, making it easier to keep the documentation up-to-date as the code evolves.

To get started with Scribble, you can install Racket and follow the documentation available on the official website: https://docs.racket-lang.org/scribble/index.html.
