  We give a simple tutorial introduction to the Mathematica package
STRINGVACUA, which is designed to find vacua of string-derived or inspired
four-dimensional N=1 supergravities. The package uses powerful
algebro-geometric methods, as implemented in the free computer algebra system
Singular, but requires no knowledge of the mathematics upon which it is based.
A series of easy-to-use Mathematica modules are provided which can be used both
in string theory and in more general applications requiring fast polynomial
computations. The use of these modules is illustrated throughout with simple
examples.
