Cluster configuration

For now, you can only use a very restricted set of commands, because we have not yet configured our client how to communicate with the Accio cluster. Configuration is done inside a clusters.json file, that is searched in two locations:

• /etc/accio/ for system-wide configuration (can be overriden with the ACCIO_CONFIG_ROOT environment variable);
• ~/.accio/ for user-specific configuration. This path cannot be overriden.

You may define multiple clusters, each one having at least a name and an address where to contact it. Clusters defined in these two files are merged, the latter file having the precedence in case of a cluster defined in both files. The first cluster ever defined is the default cluster, that is used if none is explicitly given.

A simple configuration file looks like this:

[{
  "name": "default",
  "server": "192.168.50.4:9999"
}]

Each cluster is a JSON object formed of the following fields.
