[R] boxplot $conf

Could anybody tell me how the boxplot-function calculates the upper
lower extremes of the notch contained in $conf which I assume is the
confidence interval? Is it reliable for data which is not normally
distributed? If not, how can I calculate and boxplot a specific
confidence interval for not normally distributed data in R (increasing
the sample size does not normalize the sample distribution)?
Any help would be greatly appreciated.
