From the developer:
Dacapo is a total energy program based on density functional theory. It uses a plane wave basis for the valence electronic states and describes the core-electron interactions with Vanderbilt ultrasoft pseudo-potentials.
For an overview see the Pseudopotential_Library page. Calculations using dacapo are done using the Atomic Simulation Environment (ASE).
You may want to check out more software, such as CAEFEM, Photometric Toolbox32 or GenealogicaGrafica, which might be similar to Dacapo.
