% Utility-file
%
% 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.
\edef\utilityversion{1998.07.07} % was: 1996.03.15 % status variables
\edef\utilityversion{1998.12.20} % was: 1998.07.07 % index attributes
\edef\utilityversion{2003.07.19} % was: 1998.12.20 % object pages
\edef\utilityversion{2006.06.23} % was: 2003.07.19 % -- instead of :
\edef\utilityversion{2006.09.21} % pt in pos
\edef\utilityversion{2008.10.14} % moved more to lua in mkiv
% Bepaalde commando's worden als string weggeschreven. Deze
% zijn aan het eind van deze file gedefinieerd.
