+// Package httpunix provides a HTTP transport (net/http.RoundTripper)
+// that uses Unix domain sockets instead of HTTP.
+//
+// This is useful for non-browser connections within the same host, as
+// it allows using the file system for credentials of both client
+// and server, and guaranteeing unique names.
+//
+// The URLs look like this:
+//
+//     http+unix://LOCATION/PATH_ETC
+//
+// where LOCATION is translated to a file system path with
+// Transport.RegisterLocation, and PATH_ETC follow normal http: scheme
+// conventions.
