+ * This file sets up some defs (particularly struct noderef) needed for
+ * the tikz parser and its users.
+ *
+ * It is needed because we wish to support bison 2.3, which is the
+ * version shipped with OSX.  bison 2.4 onwards allows us to put this
+ * stuff in a "%code requires" block, where it will be put in the
+ * generated header file by bison.
+ *
+ * All the types used by the %union directive in tikzparser.ym should
+ * be declared, defined or imported here.
