# --------------------------------------------------------------------------- #
# Dave Richerby's wonderful LaTeX makefile                                    #
# --------------------------------------------------------------------------- #

# This makefile is in the public domain.  Do whatever you want with it
# but be aware that it is provided ``as is'' without any express or
# implied warranty.
#
# Please mail comments or suggestions to davidr@chiark.greenend.org.uk
#
# Examples of usage:
#   ``make foo.ps'':    compile foo.tex to PostScript
#   ``make foo'':       compile foo.tex to PostScript and view it
#   ``make foo.ps.gz'': compile foo.tex to PostScript and compress it
#
# Warning: don't cut and paste this file from your browser as it will
# probably convert all the tabs to spaces.  The make program needs
# them to be tabs.
#
# Changes:
#
# 2000-10-18: Added PDF output (thanks to chrisw@chiark.greenend.org.uk)
# 2000-10-12: Original version


#
# Set this to your PostScript viewer
#
VIEWER=evince

#
# If you want a default action, put it here.  E.g. ``default: foo.ps''
# will cause make to produce foo.ps when run without arguments
#

DOCUMENT1=processes-lg
DOCUMENT2=posix-threads
DOCUMENT3=windows-threads
DOCUMENT4=processes

default: $(DOCUMENT1).pdf $(DOCUMENT2).pdf $(DOCUMENT3).pdf $(DOCUMENT4).pdf \
	$(DOCUMENT1).dvi $(DOCUMENT2).dvi $(DOCUMENT3).dvi \
	$(DOCUMENT4).dvi $(DOCUMENT2)-solns.dvi $(DOCUMENT2)-solns.pdf \
        publish


#
# If you have any documents which include other files, list them here, e.g.
#
#   sample.dvi: sample.tex diagram.eps
#
# If you need to continue onto a second line, end the first with a '\'
# character
#


# --------------------------------------------------------------------------- #
# You shouldn't need to change anything below this point unless you're        #
# extending the functionality of the makefile.                                #

# 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. ps2pdf -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 ps2pdf 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.
