-//!
-//! This crate provides a CLI that starts services for [Typst](https://typst.app/). It provides:
-//! + `tinymist lsp`: A language server following the [Language Server Protocol](https://microsoft.github.io/language-server-protocol/).
-//! + `tinymist preview`: A preview server for Typst.
-//!
-//! ## Usage
-//!
-//! See [Features: Command Line Interface](https://myriad-dreamin.github.io/tinymist/feature/cli.html).
-//!
-//! ## Documentation
