+// Package extensions provides information and interaction with the different extensions available
+// for an OpenStack service.
+//
+// The purpose of OpenStack API extensions is to:
+//
+// - Introduce new features in the API without requiring a version change.
+// - Introduce vendor-specific niche functionality.
+// - Act as a proving ground for experimental functionalities that might be included in a future
+//   version of the API.
+//
+// Extensions usually have tags that prevent conflicts with other extensions that define attributes
+// or resources with the same names, and with core resources and attributes.
+// Because an extension might not be supported by all plug-ins, its availability varies with deployments
+// and the specific plug-in.
