hyp looks up the German
Wiktionary to figure out how to hyphenate
words and outputs in a TeX compatible format:
% hyp Transistor
Tran\-si\-stor
% hyp Determinativkompositum
De\-ter\-mi\-na\-tiv\-kom\-po\-si\-tum
It also works for some foreign words, because the German(!) Wiktionary actually contains a few entries for some other languages as well (unfortunately, other Wiktionary editions don’t have hyphenation data):
% hyp apple
ap\-ple
NP: Die Schnitter—Thomas Müntzer
