Generate multiple target using single action/rule

Question

How do I write a rule to generate set of files using a single action.

Example: Files x, y, z are generated as a result of single execution of script t.sh which takes file a as input.

x y z: a
    t.sh $@

GNU make tries to execute t.sh 3 times.

Thanks for pointing! :) It was difficult to search for this question in archives. — shoban, Jul 20 '10 at 14:25

You could implement one of the solutions specified in the automake manual.

Because you've tagged this gnumake, I should also point out that using a GNU make pattern rule (the ones with %) with multiple targets WILL consider both generated from one execution of the rule: see the GNU make manual.
