+Ein Vortrag von \fBMarkus Schnalke\fP
+über die wahre Genialität von Unix.
+.P
+Unix ist ein beeindruckendes Betriebssystem und eine 
+erstklassige Programmsammlung.
+Doch dies ist beides letztlich nur eine Folge.
+\fIDas eigentlich besondere an Unix ist seine Philosophie.\fP
+Die Unix Philosophie ist eine Sammlung von Konzepte und
+Designziele die in Unix umgesetzt wurden.
+.P
+Dieser Vortrag wird die Unix Philosophie vorstellen
+und erklären weshalb sie zu hervorragender Software führt.
+.P
+Neben den rein technischen Aspekten bietet die
+Unix Philosophie aber auch Anreize für das tägliche Leben.
+Sie ist mehr als Richtlinien um gute Software zu erzeugen,
+sie ist eine Inspiration in vielerlei Hinsicht.
