  The codes HFgradZ.py and HFgradT.py find axially symmetric minima of a
Hartree-Fock energy functional for a Hamiltonian supplied in a shell-model
basis. The functional to be minimized is the Hartree-Fock energy for
zero-temperature properties or the Hartree-Fock grand potential for
finite-temperature properties. Various constraints may be imposed on the
minima.
