The package in question is downgraded to an experimental one.
A robust and efficient replacement, implementing modular decomposition
of graphs (and digraphs), for the corresponding functionality would be
great.
Perhaps this should be made a GSoC project?

Dear sir,
there is an error concerning the function "is_prime" for graphs in
Sagemath, section Graph Theory.
Here is a conter-example.
g1=Graph({0:[1,4],1:[0,2,4],2: [1,3,4],3:[2],4:[0,1,2]});g2=G
raph({0:[1],1:[0,2,4],2:[1,3,4 ],3:[2,4],4:[1,2,3]})
#g1.show();g2.show();
#[1,4] is a modul
