+     * appropriately for variable bindings.
+     *
+     * NetworkAccessDelegator is an indirection mechanism which takes care of
+     * the fact that QIODevice instances are injected into the data model by
+     * having them represented using a URI. managerFor() returns appropriately
+     * the right network access manager depending on whether the URI refers to
+     * a variable, or to something else.
+     *
+     * The constructor take a pointer to two NetworkAccessDelegator instances.
+     * First is a generic one, the second is the one which handles variable
+     * bindings. managerFor() then returns the appropriate one depending on the
+     * URI.
