-//! The compiler for the _Typst_ markup language.
-//!
-//! # Steps
-//! - **Parsing:**
-//!   The compiler first transforms a plain string into an iterator of [tokens].
-//!   This token stream is [parsed] into a [syntax tree]. The tree itself is
-//!   untyped, but the [AST] module provides a typed layer over it.
-//! - **Evaluation:**
-//!   The next step is to [evaluate] the markup. This produces a [module],
-//!   consisting of a scope of values that were exported by the code and
-//!   [content], a hierarchical, styled representation of what was written in
-//!   the source file. The elements of the content tree are well structured and
-//!   order-independent and thus much better suited for further processing than
-//!   the raw markup.
-//! - **Typesetting:**
-//!   Next, the content is [typeset] into a [document] containing one [frame]
-//!   per page with items at fixed positions.
-//! - **Exporting:**
-//!   These frames can finally be exported into an output format (currently
-//!   supported are [PDF] and [raster images]).

-/// The environment in which typesetting occurs.
-///
-/// All loading functions (`main`, `source`, `file`, `font`) should perform
-/// internal caching so that they are relatively cheap on repeated invocations
-/// with the same argument. [`Source`], [`Bytes`], and [`Font`] are
-/// all reference-counted and thus cheap to clone.
-///
-/// The compiler doesn't do the caching itself because the world has much more
-/// information on when something can change. For example, fonts typically don't
-/// change and can thus even be cached across multiple compilations (for
-/// long-running applications like `typst watch`). Source files on the other
-/// hand can change and should thus be cleared after. Advanced clients like
-/// language servers can also retain the source files and [edited](Source::edit)
-/// them in-place to benefit from better incremental performance.
