<Colophon>
&XMod; was originally implemented in 1997 using the &GAP;3 language.
when the first author was studying for a Ph.D. <Cite Key="A1"/> in Bangor.
<P/>
In April 2002 the first and third parts were converted to &GAP;4, 
the pre-structures were added, and version 2.001 was released. 
The final two parts, covering derivations, sections and actors, 
were included in the January 2004 release 2.002 for {\GAP}~4.4.
<P/>
The current version is 2.008, released on October 25th 2006. 
<P/>
Bug reports, suggestions and comments are, of course, welcome. 
Please contact the second author at
