While checking how to use the cassandra connection, the documentation instructs to add this to the sbt file:

```
"libraryDependencies += "com.datastax.spark" %% "spark-cassandra-connector" % "1.6.0-M1"

```

In general, is there an obvious, straight forward logic to translate this into the corresponding:

```
spark-shell --packages "field1":"field2"

```

I've tried:

```
spark-shell --packages "com.datastax.spark":"spark-cassandra-connector"

```

and a few other things but that doesn't work.
