[edit] Track-To

The Track-To constraint lets you influence the Rotation of the constrained object by making it track a target with one of the constrained object's axis.

[edit] The Constraint Panel

• You can enter the name of the target you want to track.
• You can select which axis is going to track the target.

Another example with armature would be the eyes of a character:
