%description
Calculates, via simulation, power and appropriate stopping alpha
boundaries (and/or futility bounds) for sequential analyses (i.e., group
sequential design) as well as for multiple hypotheses (multiple tests
included in an analysis), given any specified global error rate. This
enables the sequential use of practically any significance test, as long
as the underlying data can be simulated in advance to a reasonable
approximation. Lukács (2022) <doi:10.21105/joss.04643>.
