## Overview

`migrate_cpp` assists in migration of C++ code to Carbon. It's currently being
assembled; more documentation will be added later.

## Structure

The `migrate_cpp` tool uses a `clang::RecursiveASTVisitor` to traverse Clang's
AST and, to each node, associate replacements. Each node's replacement is a
sequence of text, or a reference to some other node that should be used to
replace it.
