+/* 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.  */
