// This crate crawls the Syn source directory to find all structs and enums that
// form the Syn syntax tree.
//
// A machine-readable representation of the syntax tree is saved to syn.json in
// the repo root for other code generation tools to consume. The syn-codegen
// crate (https://docs.rs/syn-codegen/) provides the data structures for parsing
// and making use of syn.json from Rust code.
//
// Finally this crate generates the Visit, VisitMut, and Fold traits in Syn
// programmatically from the syntax tree description.
