Algebraic Reduction of Feynman Diagrams to Scalar Integrals: a   Mathematica implementation of LERG-I
  A Mathematica implementation of the program LERG-I is presented that performs the reduction of tensor integrals, encountered in one-loop Feynman diagram calculations, to scalar integrals. The program was originally coded in REDUCE and in that incarnation was applied to a number of problems of physical interest.
