scripts

Basic scripts to deploy and run HovercRaft for the synthetic and Redis experiments.

To get the dependencies and build an example run:

git submodule update --init --recursive
make hovercraft-stss

Check the Makefile for more build options.

Check the scipts directory for running experiments. Configure the fabfile.py and driver.py scripts accordingly.
