Well, GNU make supports wildcards and expressions and other such features to
make your makefile more modular. Some other make implementations have similar
feature, but I have little experience with these make clones.
Here's an example:
{{{{{{{{{{{
EPSES = boule-base.eps graph-3.eps logo.eps
PDFS = $(patsubst %.eps,%.pdf,$(EPSES))
all: to_pdf
to_pdf: $(PDFS)
$(PDFS): %.pdf: %.eps
epstopdf --outfile=$@ $<
}}}}}}}}}}
If you're looking for an arbitray key->value mapping, you should look at
http://gmsl.sourceforge.net/ 's associative arrays.
