I'm learning to work with GNU make and I'm reading the manual (which is very good) but I'm missing a cheat-sheet for quick reference. Is there any good?

$@ is the name of the target being generated, and $< the first prerequisite (usually a source file). You can find a list of all these special variables in the GNU Make manual.
The @ symbol is commonly seen at the beginning of an action lines and means that the action line itself is not be be echoed on the screen as it is executed. Macros are commonly used in makefiles to decrease the amount of typing required.
