+% Beste lezers, kijk,
+%
+% Een bolletje hebben we bij toeval allemaal wel eens getekend, maar begint u
+% toch eenvoudig. Eerst een eenvoudig kruis of herstellingsteken
+% en via de dubbelslag naar een voorzichtig vlaggetje, en heb geduld!
+% Ikzelf heb bijvoorbeeld over mijn eerste gave G-sleutel
+% 35 kilobyte metafont, 12 patchlevels, 0 vriendinnen en 45 dagen gedaan
