// Package cue is the main API for CUE evaluation.
//
// Value is the main type that represents CUE evaluations. Values are created
// with a cue.Context. Only values created from the same Context can be
// involved in the same operation.
//
// A Context defines the set of active packages, the translations of field
// names to unique codes, as well as the set of builtins. Use
//
//     import "cuelang.org/go/cue/cuecontext"
//
//     ctx := cuecontext.New()
//
// to obtain a context.
//
//
// Note that the following types are DEPRECATED and their usage should be
// avoided if possible:
//
//    FieldInfo
//    Instance
//    Runtime
//    Struct
//
// Many types also have deprecated methods. Code that already uses deprecated
// methods can keep using them for at least some time. We aim to provide a
// go or cue fix solution to automatically rewrite code using the new API.
