STRINGVACUA for Mathematica

James Gray, Yang-Hui He, Anton Ilderton, and André Lukas have created a package for Mathematica that analyzes potentials in N=1 supergravity (usually convoluted ratios of polynomials in fields), their critical points, and constraints necessary for a low-energy model to generate semi-realistic vacua.
Tutorial: preprint (PDF)
Installation instructions
The system can filter vacua according to their number of flat directions (for example, you can suppress all non-stabilized vacua) or according to inequalities imposed on field values and it determines the number of negative directions etc. Non-perturbative i.e. non-polynomial (usually exponential) terms may be added and represented by dummy variables.
