It has been written in Mathematica 6.0 but it can be easily modified to be run in some earlier version of Mathematica. To optimize computations elements of the Weyl algebra are treated as polynomials. Several procedures which order the terms are included. The program is available at the web page http://cpc.cs.qub.ac.uk/summaries/AEBU_v1_0.html9 pages. Revised version. Notation has been modifiedMathematical Physics53D55text
