The software requires some Cabal packages to be run, all the required dependencies are listed in "quipks.cabal".
Running
ghc Main.hs
produces an executable which outputs a string that is the .dot representation of the graph.
You can use
./Main > mygraph.dot
followed by
dot -Tps mygraph.dot -o mygraph.pdf
and then open your pdf file.
You'll need Graphviz to visualize the .dot files: http://www.graphviz.org/
Note: parametrized gates aren't supported yet.
