 Macro expansion happens during parsing. `rustc` has two parsers, in fact: the
 normal Rust parser, and the macro parser. During the parsing phase, the normal
-Rust parser will call into the macro parser when it encounters a macro
-definition or macro invocation (TODO: verify). The macro parser, in turn, may
-call back out to the Rust parser when it needs to bind a metavariable (e.g.
-`$my_expr`) while parsing the contents of a macro invocation. The code for macro
-expansion is in [`src/libsyntax/ext/tt/`][code_dir]. This chapter aims to
-explain how macro expansion works.
