- Generate norm-conserving pseudopotentials of the Hammann  and Troullier-Martins  types, employing common parameterizations of the local-density approximation and generalized gradient approximations for exchange and correlation.
- Check the transferability of one's pseudopotentials, in particular
to search for unphysical ghost states
of their fully separable (Kleinman-Bylander) representation .
- Spin-polarized atoms can be calculated, and pseudopotentials for exact Kohn-Sham exchange calculations can be produced. These features are at a developmental stage and require care.
A database of generic input data files for most elements is part of this package. General background about pseudopotentials and practical considerations for generating them may be found in . A hands-on tutorial and worked-out examples are available as well.
Unix c-shell scripts serve as command-line interfaces to facilitate the above tasks. Their pseudopotential output is compatible with the input format of the fhimd program  and can be readily adjusted to fit other codes. For visual inspection of results, these scripts provide graphics files to be viewed with the public domain plotting tool XMGRACE.
