+We guarantee the libguestfs ABI (binary interface), for public,
+high-level actions as outlined in this section.  Although we will
+deprecate some actions, for example if they get replaced by newer
+calls, we will keep the old actions forever.  This allows you the
+developer to program in confidence against libguestfs.
