+% De onderstaande macro's ondersteunen het gebruik van de
+% zogeheten utility-file. Alle extern onder te brengen
+% informatie wordt opgeslagen in de file \jobname.tui, tenzij
+% er selectief pagina's worden gezet. In dat geval wordt de
+% file \jobname.tmp gebruikt. Informatie wordt ingelezen uit
+% de file \jobname.tuo, welke door TeXUtil wordt aangemaakt.
