   <Abstract>
     The &groupoids; package provides functions for computation with
 groupoids (categories with every arrow invertible) and their morphisms; for 
graphs of groups, and graphs of groupoids.
 The most basic structure introduced is that of <E>magma with objects</E>, 
followed by <E>semigroup with objects</E>, then <E>monoid with objects</E> and 
finally <E>groupoid</E> which is a <E>group with objects</E>.
- <P/>It provides normal forms for Free Products with Amalgamation and for 
HNN-extensions when the initial groups have rewrite systems and the subgroups 
have finite index. This is described in Section <Ref Sect="sec-gphgps"/>. It is 
planned to move this section to a new package <Package>Rewriting</Package> in 
time for version 4.11 of &GAP;.
-<P/>The &groupoids; package was originally implemented in 2000 (as 
<Package>GraphGpd</Package>) when the first author was studying for a Ph.D. in 
Bangor.
