Now all those $@ thingees that appear in the example above and elsewhere in the makefile are clearly not plain old macros, since they're never defined and yet this makefile works quite well, I promise. The reason is that there are a number of special macros with one character names that are only useable as part of a dependency rule:

$@
The file name of the target.
$<
The name of the first dependency.
$*
The part of a filename which matched a suffix rule.
$?
The names of all the dependencies newer than the target separated by spaces.
$^
The names of all the dependencies separated by spaces, but with duplicate names removed.
$+
The names of all the dependencies separated by spaces with duplicate names included and in the same order as in the rule.
