   /**
-     Internal helper for implementing xVtab and xCursor.
-     The first argument must be the logical name of the
-     handler ('xVtab' or 'xCursor') and the second must be
-     the capi.XYZ struct-type value, e.g. capi.sqlite3_vtab
-     or capi.sqlite3_vtab_cursor.
+     A factory function which implements a simple lifetime manager for
+     mappings between C struct pointers and their JS-level wrappers.
+     The first argument must be the logical name of the manager
+     (e.g. 'xVtab' or 'xCursor'), which is only used for error
+     reporting. The second must be the capi.XYZ struct-type value,
+     e.g. capi.sqlite3_vtab or capi.sqlite3_vtab_cursor.
+
+     Returns an object with 4 methods: create(), get(), unget(), and
+     dispose(), plus a StructType member with the value of the 2nd
+     argument. The methods are documented in the body of this
+     function.
