  Recent work, using an effective field theory framework, has shown the number
of possible couplings between nucleons and the dark-matter-candidate Weakly
Interacting Massive Particles (WIMPs) is larger than previously thought.
Inspired by an existing Mathematica script that computes the target response,
we have developed a fast, modern Fortran code, including optional OpenMP
parallelization, along with a user-friendly Python wrapper, to swiftly and
efficiently explore many scenarios, with output aligned with practices of
current dark matter searches. A library of most of the important target
nuclides is included; users may also import their own nuclear structure data,
in the form of reduced one-body density matrices. The main output is the
differential event rate as a function of recoil energy, needed for modeling
detector response rates, but intermediate results such as nuclear form factors
can be readily accessed.
