Syntax-Hervorhebung

DokuWiki kennt Syntax highlighting für Quellcode, um dessen Lesbarkeit zu erhöhen. Dafür wird GeSHi „Generic Syntax Highlighter“ benutzt. Somit wird jede Programmiersprache unterstützt, die GeSHi kennt. Es wird der Bezeichner code benutzt, und man muss nur den Namen der gewünschten Sprache angeben:
