SARAH is a Mathematica package for building and analyzing supersymmetric theories. SARAH just needs the gauge structure, particle content and superpotential to produce all information about the gauge eigenstates of a model. Breaking of gauge symmetries and mixings of particles can easily be added. Also the gauge fixing terms can be specified, and the corresponding ghost interactions are calculated automatically. SARAH can write all information about the model in LaTeX, or create a model file for FeynArts and CalcHep/CompHep, which can also be used for dark matter studies using MicrOmegas. In addition, also analytical results for the one and two loop renormalization group equations for for the parameters of the superpotential, the gauge couplings and the soft breaking parameters can be calculated. Also functions for an automatic calculation for the one loop corrections to self energies and the tadpoles are included. The intention by the development of SARAH was to make it very flexible: There is a big freedom for the matter and gauge sector you can handle. The work with SARAH should be easy: Every information SARAH needs are specified in an easy to modify model file. Nevertheless, SARAH is also fast: A existing model can be changed within minutes, and the needed time for doing all necessary calculations and writing a model file is normally less than 10 minutes.
