+// Capsule creates a new Capsule type.
+//
+// A Capsule type is a special type that can be used to transport arbitrary
+// Go native values of a given type through the cty type system. A language
+// that uses cty as its type system might, for example, provide functions
+// that return capsule-typed values and then other functions that operate
+// on those values.
+//
+// From cty's perspective, Capsule types have a few interesting characteristics,
+// described in the following paragraphs.
+//
+// Each capsule type has an associated Go native type that it is able to
+// transport. Capsule types compare by identity, so each call to the
+// Capsule function creates an entirely-distinct cty Type, even if two calls
+// use the same native type.
+//
+// Each capsule-typed value contains a pointer to a value of the given native
+// type. A capsule-typed value supports no operations except equality, and
+// equality is implemented by pointer identity of the encapsulated pointer.
+//
+// The given name is used as the new type's "friendly name". This can be any
+// string in principle, but will usually be a short, all-lowercase name aimed
+// at users of the embedding language (i.e. not mention Go-specific details)
+// and will ideally not create ambiguity with any predefined cty type.
+//
+// Capsule types are never introduced by any standard cty operation, so a
+// calling application opts in to including them within its own type system
+// by creating them and introducing them via its own functions. At that point,
+// the application is responsible for dealing with any capsule-typed values
+// that might be returned.
