  We present FormTracer, a high-performance, general purpose, easy-to-use
Mathematica tracing package which uses FORM. It supports arbitrary space and
spinor dimensions as well as an arbitrary number of simple compact Lie groups.
While keeping the usability of the Mathematica interface, it relies on the
efficiency of FORM. An additional performance gain is achieved by a
decomposition algorithm that avoids redundant traces in the product tensors
spaces. FormTracer supports a wide range of syntaxes which endows it with a
high flexibility. Mathematica notebooks that automatically install the package
and guide the user through performing standard traces in space-time, spinor and
gauge-group spaces are provided.
