laterite-admin 0.8.2

//! Boot-time assembly of the field-type registry. Imports only the public API.
//!
//! The reference field cannot come from the arg-free built-ins: it needs the
//! picker registry, so boot inserts it into the registry separately. Anything
//! that rebuilds the registry after that point silently drops it, and every form
//! using a reference field then fails to boot.
