### Passing configuration to a verticle

Configuration in the form of JSON can be passed to a verticle at deployment time:

    config = {
     'name' => "tim",
     'directory' => "/blah"
    }
    options = {
     'config' => config
    }
    vertx.deploy_verticle("MyOrderProcessorVerticle.rb", options)

This configuration is then available via the `Context` object.

The configuration is returned as a Hash object so you can retrieve data as follows:

    puts $vertx.get_or_create_context().config()["name"]

### Accessing environment variables in a Verticle

Environment variables and system properties are accessible from a verticle using the Java API:

    puts Java::JavaLang::System.getProperty("foo")
    puts Java::JavaLang::System.getenv("HOME")
