  I discuss the various available tools for the study of the properties of the
new particles predicted in the Minimal Supersymmetric extension of the Standard
Model. Emphasis will be put on the codes for the determination of the sparticle
and Higgs boson spectrum. Codes for the calculation of production cross
sections, decay widths and branching ratios, Dark Matter relic density and
detection rates, as well as codes for automatic analytical calculations and
Monte-Carlo event generators for Supersymmetric processes will be briefly
discussed.
