#   D: Makefile zum Erzeugen eines 3x2-Faltblattes.
#   E: Makefile to create a 3 x 2 folded leaflet
#   D: Siehe die Kommentare am Anfang von leaflet.tex.
#   E: See commentary at beginning of ...
#
#   D: Folgende Ports muessen installiert sein (in Klammern
#   D: die Version, mit der es getestet ist und funktioniert):
#   E: Following (FreeBSD) ports must be installed (in brackets
#   E: the version it was tested & functions with)
#
#	print/teTeX	     (teTeX-1.0.7)
#	print/ghostscript6   (ghostscript-6.50_6)
#		jhs used on FreeBSD-4.7:	print/ghostscript-gnu
#	print/psutils-a4     (psutils-a4-1.17_1)
#	print/dvips2ascii
#	textproc/ispell
#	german/ispell
#
#   E: You must also download, compile, install

#
#   D: Um die PDF-Datei am Bildschirm anzusehen, wird eines
#     der folgenden beiden benoetigt:
#   E: To see the PDF on screen you'll need one of these.
#
#      print/gv 	    (gv-3.5.8)
#      print/acroread4	    (acroread4-4.05)
#
#   D: Ich empfehle acroread4, da es eine genauere Darstellung
#      bietet (und bei eingeschaltetem Antialias schneller ist).
#      gv nimmt bei der PDF-Datei ein falsches Format.
#   E: I reccomend acroread4, as it give a better presentation,
#      & is fater if antialias enabled
#      gv with PDF give wrong format
#
#   "make"		D: erzeugt alle Dateien.
#			E: Creates all files
#   "make clean"	D: loescht alle erzeugbaren Dateien.
#			E: Deletes all created files
#   "make view" 	D: zeigt die PDF/PS-Datei an (acroread4 / gv).
#			E: Displays the result
#
