We describe a Macaulay2 package for computations in prime characteristic commutative algebra. This includes those for Frobenius powers and roots,
p^(-e)-linear and p^e-linear maps, singularities defined in terms of these maps, different types of test ideals and modules, and ideals compatible with a given
p^(-e)-linear map.
