This new package released and maintained by jjames is meant to allow users to use my upstream GRAPE package with bliss instead of nauty, as nauty is excluded from Fedora for license reasons. However, there are bugs in its GRAPE/bliss interface. In particular, incorrect automorphism groups of graphs can be returned, and the vertex colouring of graphs is incorrectly output to bliss, leading to many more errors for automorphism groups and canonical labellings of graphs coloured with more than one vertex-colour. I have sent jjames corrections to these bugs. These corrections are implemented in the attached file meant to replace the package file /usr/lib/gap/pkg/grape/lib/grape.g
