/* The format of .solv files might change incompatibly, and that is described
   by the above version number.  But sometimes we also extend the emitted
   attributes (e.g. by adding a new one for solvables, for instance patch
   category).  Consumers need to know if the .solv file they have needs to
   be regenerated by newer converters or not (or better, if regenerating them
   would give a different .solv file).  We use this serial number for that.
   We increase it every time we add or remove attributes (or change the
   interpretation of them).  Tools installed by the user will have their
   version compiled in, so they can detect mismatches between .solv files
   they see and themself.  */
