# ============================================================================ #
# Hinweis: 
# --------
# Bei FreeBSD 5 wurde das Portsverzeichnis dahingehend geändert, daß jetzt
# einige (interne) Hinweisdateien entfallen bzw. umbenannt wurden. Es entfällt
# die Datei pkg-comment, die einzeiligen Kommentare zu den Ports befinden sich,
# wie bereits in NetBSD, in der Make-Datei im Feld COMMENT.
# Diese Version des Skripts trägt dem Rechnung.
