+// This file contains a facility for generating "archetypes" of out of
+// "Conformance Profiles" (see "conformance_profiles.h" for more information
+// about Conformance Profiles). An archetype is a type that aims to support the
+// bare minimum requirements of a given Conformance Profile. For instance, an
+// archetype that corresponds to an ImmutableProfile has exactly a nothrow
+// move-constructor, a potentially-throwing copy constructor, a nothrow
+// destructor, with all other special-member-functions deleted. These archetypes
+// are useful for testing to make sure that templates are able to work with the
+// kinds of types that they claim to support (i.e. that they do not accidentally
+// under-constrain),
+//
+// The main type template in this file is the Archetype template, which takes
+// a Conformance Profile as a template argument and its instantiations are a
+// minimum-conforming model of that profile.

+// This file contains templates for representing "Regularity Profiles" and
+// concisely-named versions of commonly used Regularity Profiles.
+//
+// A Regularity Profile is a compile-time description of the types of operations
+// that a given type supports, along with properties of those operations when
+// they do exist. For instance, a Regularity Profile may describe a type that
+// has a move-constructor that is noexcept and a copy constructor that is not
+// noexcept. This description can then be examined and passed around to other
+// templates for the purposes of asserting expectations on user-defined types
+// via a series trait checks, or for determining what kinds of run-time tests
+// are able to be performed.
+//
+// Regularity Profiles are also used when creating "archetypes," which are
+// minimum-conforming types that meet all of the requirements of a given
+// Regularity Profile. For more information regarding archetypes, see
+// "conformance_archetypes.h".
