When using pattern rules (wildcards) in Makefiles, there are some
variables you can use to expand to the part of the filenames that
match the wildcards.  Example:

%.pdf : %.ps Makefile
	ps2pdf $< > $@

If we're converting "page.ps" to "page.pdf", some useful variables are
as follows:

$@	page.pdf (the target)
$<	page.ps  (the first depends-on file)
$^	"page.ps Makefile" (all depends-on files)
$*	page     (the part that matched the '%')
