  BiFold calculates the density-dependent (DDM3Y$n$, BDM3Y$n$, CDM3Y$n$) or
independent double folded potentials between two colliding spherical nuclei. It
is written in a Python package form to give the ability to use the potentials
directly in a nuclear reaction/structure code. In addition to using
Woods-Saxon/Fermi or Gaussian functions, the code also allows for the
definition of nuclear matter densities using pre-calculated densities in a data
file. The manuscript provides an overview of the double folding model and the
use of the code.
