This is a simple makefile for LaTeX sources:

### Do not change the first part                    ###
### Rules to manage tex -> dvi -> ps -> pdf  ###  
LATEX = latex
PDFLATEX = pdflatex
DVIPS = dvips
PSPDF = ps2pdf

%.dvi:	%.tex
	$(LATEX) $<
%.pdf:	%.tex
	$(PDFLATEX) $< $@
%.ps:	%.dvi
	$(DVIPS) $< -o $@
