# CUSTOM BUILD RULES

# In case you didn't know, '$@' is a variable holding the name of the target,
# '$<' is a variable holding the (first) dependency, and '$*' is a variable
# holding the string matching '%' of a rule.

%.tex: %.dat
	./dat2tex $< > $@

# MAIN LATEXMK RULE

# -pdf tells latexmk to generate PDF directly (instead of DVI).
# -pdflatex="" tells latexmk to call a specific backend with specific options.
# -use-make tells latexmk to call make for generating missing files.

# -interactive=nonstopmode keeps the pdflatex backend from stopping at a
# missing file reference and interactively asking you for an alternative.
