[libextractor] Python: libextractor

[Karsten Hilbert]

Hallo Christian,

ich muß mal eine dumme Frage stellen: Wie nutze ich
libextractor aus Python ? Hintergrund ist folgender. Die
Dokumentation im Netz ist extrem spärlich:

 "Python programmers will find that libextractor (since
  0.5.0) can also be used from Python, just import Extractor."

Aber ich kann nicht rausfinden, wie es funktoniert:
