Prüfen ob Wörter in einem String vorkommen, Reihenfolge egal

[Robert_G]

Falls du ein wenig in .Net interessiert bist...

Ich habe gerade aus "Jux" das Ganze mal in C#2.0 gebastelt (die Beta gibt's kostenlos bei M$ )
Es ist nicht wirklich "hübsch", war aber in 10 Minuten fertig. (mit "IntelliSense tippt man schneller als ein MaiKäfer husten kann )
