A unified density-functional theory for classical nonuniform systems is proposed. The theory is based on mapping the excess free energy of a nonuniform system onto that of an effective liquid; in the uniform limit, the theory reproduces the known properties of the liquid. Connection with previous density-functional theories is also established. Finally, the theory is applied to the freezing of the hard-sphere liquid, giving results in good agreement with computer simulations.
