poly of pow 2



the readme for 'format' says:
*   Notes by importer to Maxima:                             
*    This package originally included a modified pois2m.lisp  
*    file.  This file can not be included in Maxima due to    
*    the presence of a Macsyma Inc. copyright in the code.    
*    As of the inital import of the code, it does not work    
*    with the current Maxima.                                 

it actually does work on some examples, crashes others, and
gives unexpected results in yet others.
regards,
praimon
