masses of the light particles can generally be neglected in high energy processes.

The program repository contains codes for translations between different computational schemes, spectrum calculators, codes for decay widths, cross sections, low-energy and cosmological/astrophysical observables, event generators, RGE codes etc. It is an open system and the responsibility for all programs remains with the authors. It is understood that in each case the theoretical state-of-the-art precision is implemented. For communication between codes SLHA [@Skands:2003cj] is strongly recommended, which is extended in a suitable way where appropriate. SPA provides the translation tables and the links to the computer codes on the SPA web page.

The tasks of the SPA Project aim at higher-order calculations, better understanding of ${{\overline{DR}}}$/${{\overline{MS}}}$ connections, improvements of experimental and theoretical precision, investigations of LHC/ILC synergy, cold dark matter, developments and explorations of beyond the MSSM scenarios etc. Since the goal of the SPA Project is to reconstruct the fundamental structure of the supersymmetric theory at the high scale, the precise understanding and the combination of all information, that will become available from collider and low-energy experiments and astrophysical/cosmological observations, will be required.
