Does calm emotions end Bbn rage, or just suppress it?

[Arc]

As a frenzied berserker's frenzy is treated for most purposes as an equivilent of a barbarian's rage, this may be the ultimate solver to the party killing frenzied berserker problem. A bard or cleric in the party with a few of these memorized/heightened (to increase will save DC), and the post combat rampage problem is solved.
