%description
Functions to calculate exact critical values, statistical power, expected
time to signal, and required sample sizes for performing exact sequential
analysis. All these calculations can be done for either Poisson or
binomial data, for continuous or group sequential analyses, and for
different types of rejection boundaries. In case of group sequential
analyses, the group sizes do not have to be specified in advance and the
alpha spending can be arbitrarily settled.
