/**
* @file namestore/plugin_gtk_namestore_box.c
* @brief namestore plugin for editing BOXed records
* @author Christian Grothoff
*
* This code is a bit hackish, as we re-use the existing logic for the
* boxed type. This is done by switching on the record type of the
* box -- and by including the code of the other plugins in this
* code, and the widgets of the other plugins in the XML for the box
* plugin. This is particularly hackish as we then need to make sure
* that the names of the shared widgets and callbacks are identical
* across the different plugins that are being boxed. This currently
* affects the SRV and TLSA plugins.
