+/* Split file handling with pivot tables.
+
+ When SPLIT FILE is in effect with the LAYERED option, values for the split
+ file variables need to be incorporated into pivot table output. These
+ functions make that easier.
+
+ To use them:
+
+ 1. After adding the rest of the dimensions to an output pivot table, call
+ pivot_splits_create(). If there are any and LAYERED mode is in use, then
+ pivot_splits_create() will add a dimension for each split file
+ variable and return a structure. Otherwise, it returns NULL.
+
+ 2. Before adding data to the pivot table for each SPLIT FILE group, call
+ pivot_splits_new_split(), passing in an example case from the group (the
+ first or last case is fine). This will the split file handler add
+ categories for the group to the split dimensions.
+
+ pivot_splits_new_split() does nothing if given a null pivot_splits, so
+ it's fine to call it unconditionally.
+
+ 3. Use pivot_splits_put*(), instead of pivot_table_put*(), to add data to
+ the pivot table. These functions automatically add the current group
+ leaf indexes after the indexes passed in, as a convenience.
+
+ These functions still work fine if given a null pivot_splits, so it's
+ fine to use them in all cases.
+
+ 4. Destroy the pivot_splits with pivot_splits_destroy() when the pivot table
+ has been fully constructed. */
