Abstract
This note describes a \emph{Macaulay2} package for computations in prime characteristic commutative algebra. This includes Frobenius powers and roots, -linear and -linear maps, singularities defined in terms of these maps, different types of test ideals and modules, and ideals compatible with a given -linear map.

Comments
21 pages, minor improvements throughout. This paper is the companion to the the latest version of the package (https://github.com/kschwede/Workshop-2017-Berkeley/tree/master/Fsing/TestIdealsPackage), which should be included in 1.15 of Macaulay2 and later
