If you want to have an visual output of your tree, you need to know the
filename and the position of the root node.

erl -pa PATH-TO-COUCHDB-BEAM-FILES -noshell -s run_vtreeviz run -s init stop -file /tmp/randtree.bin -pos 7581

The output is a Graphviz dot file. Create a PNG out of it with:
dot -Tpng -o randtree.png YOUR-DOT-FILE


If you want to run the vtree tests:
go to build dir and:
erl -pa PATH-TO-COUCHDB-BEAM-FILES -pa PATH-TO-ETAP-BEAM-FILES -noshell -s vtree_test start -s init stop
