BNDASA: Calculates energy bands and evaluates the moments.
TETRA: Sets up the k-points and weights for k-space integration using the tetrahedron method.
SAMPLE: k-space integration by sampling.
MAD: Evaluates the Madelung potential and energy.
DENS: Calculates full charge density and the ELF.
RHONS: Makes a fit to the full charge density.
SYM: Generates all operations in a space group from a set of generators. This is used to determine the k-points in the irreducible part of the Brillouin zone, and to symmetrize the density matrix which is only calculated in the irreducible BZ.
