# -*- makefile -*-

# This makefile is useful for compiling lab sheets for LPI courses.
# Just copy into the directory as is; there is no need to edit it at all.
# It assumes that each *.tex file is to generate one pdf file.
# It also assumes that each output file depends on all the *.fig files.

# It does not process the file with lgrind first; see my Makefile
# for c-for-engineers for that.
# It is not designed for producing beamer slides.
# See my Makefile for beamer-slides for that.

# DON'T Cancel the built in rule that uses tex to produce dvi files:
# %.dvi: %.tex

# See http://freshmeat.net/articles/view/667/
#    1. latex file.tex
#    2. dvips -Ppdf -G0 file.dvi -o file.ps
#    3. ps2pdf13 -dPDFsettings=/prepress file.ps file.pdf 

# Two points to note:

#     * The -G0 parameter passed to dvips is used to get around a
#       bug in GhostScript which converts the "f" character to a
#       pound sign in the final PDF.

#     * The -dPDFsettings parameter for ps2pdf13 is used to prevent
#       downsampling of EPS images when they are converted to PDF.
#       Without this switch, EPS graphics in the final PDF look
#       very fuzzy, especially when viewed with a projector.
