The LibratoReporter class runs in the background, publishing metrics from codahale/metrics to the Librato Metrics API at the specified interval.

During the initialization of your program, simply use the .enable method with the appropriately configured LibratoReporter.Builder class. See the setters on that method for all the available customizations (there are quite a few). The constructor for the Builder requres only the things that are necessary; sane defaults are provided for the rest of the options.
LibratoReporter.enable(LibratoReporter.builder("<Librato Username>", "<Librato API Token>", "<Source Identifier (usually hostname)>"), 10, TimeUnit.SECONDS);
Since this project depends heavily on metrics-core, the version number will be <version of metrics-core being depended on>.<release number of the reporter>. Thus, the first release will be version 2.1.2.0, as 2.1.2 is the current stable version of metrics-core. If this proves impractical, a different versioning scheme will be investigated.
