-//! Write the output of rustc's analysis to an implementor of Dump.
-//!
-//! Dumping the analysis is implemented by walking the AST and getting a bunch of
-//! info out from all over the place. We use `DefId`s to identify objects. The
-//! tricky part is getting syntactic (span, source text) and semantic (reference
-//! `DefId`s) information for parts of expressions which the compiler has discarded.
-//! E.g., in a path `foo::bar::baz`, the compiler only keeps a span for the whole
-//! path and a reference to `baz`, but we want spans and references for all three
-//! idents.
-//!
-//! SpanUtils is used to manipulate spans. In particular, to extract sub-spans
-//! from spans (e.g., the span for `bar` from the above example path).
-//! DumpVisitor walks the AST and processes it, and Dumper is used for
-//! recording the output.
