The IdRel package is designed for computing the identities among relations 
of a group presentation using rewriting, logged rewriting, 
monoid polynomials, module polynomials and Y-sequences.

Version 1.001 of ``IdRel'' formed part of Anne Heyworth's PhD thesis in

and deposited in the incoming directory on the St Andrews ftp server.
A more detailed history will be included as Chapter 6 of the manual.
Version 2.04 was released on 14th November 2008, 
where the main change was the move to a new package website.  
The latest version, jusdt fixing file permissions, 
is 2.05 released 21st November 2008. 

The ``IdRel'' package is distributed with the deposited GAP packages.
