[luatex] Hinweis auf luatex Digest, Vol 94, Issue 12

[Juergen Pfitzenmaier]

Hallo Alex,
das ist Teil einer aktuellen Diskussion. Und könnte Deinen
Wunsch nach ant oder etwas ähnlichem erfüllen. Da baut
jemand auf der aktuellen luatex eine allgemeine Printengine,
die man von außen steuern kann -- siehe die Bemerkung
ganz am Ende der Meldung.

Viele Grüße
Jürgen
