calculus - Computing the integral of $log(sin x)$

How to compute the following integral?
$$\int\log(\sin x)\,dx$$

---

Motivation: Since $\log(\sin x)'=\cot x$, the antiderivative $\int\log(\sin x)\,dx$ has the nice property $F''(x)=\cot x$. Can we find $F$ explicitly? Failing that, can we find the definite integral over one of intervals where $\log (\sin x)$ is defined?
