+* `quote_attr!`
+
+Keep in mind that when `$name : ident` appears in the input to
+`quote_tokens!`, the result contains unquoted `name` followed by two tokens.
+However, input of the same form passed to `quote_matcher!` becomes a
+quasiquoted MBE-matcher of a nonterminal. No unquotation happens. Otherwise
+the result of `quote_matcher!` is identical to that of `quote_tokens!`.
Documentation is very limited at the moment.

+/// Imports the codemap from an external crate into the codemap of the crate
+/// currently being compiled (the "local crate").
+///
+/// The import algorithm works analogous to how AST items are inlined from an
+/// external crate's metadata:
+/// For every FileMap in the external codemap an 'inline' copy is created in the
+/// local codemap. The correspondence relation between external and local
+/// FileMaps is recorded in the `ImportedFileMap` objects returned from this
+/// function. When an item from an external crate is later inlined into this
+/// crate, this correspondence information is used to translate the span
+/// information of the inlined item so that it refers the correct positions in
+/// the local codemap (see `astencode::DecodeContext::tr_span()`).
+///
+/// The import algorithm in the function below will reuse FileMaps already
+/// existing in the local codemap. For example, even if the FileMap of some
+/// source file of libstd gets imported many times, there will only ever be
+/// one FileMap object for the corresponding file in the local codemap.
+///
+/// Note that imported FileMaps do not actually contain the source code of the
+/// file they represent, just information about length, line breaks, and
+/// multibyte characters. This information is enough to generate valid debuginfo
+/// for items inlined from other crates.
