Version 0.3 of Gmetrics is out now.

The project provides calculation and reporting of size and complexity metrics for Groovy source code, by scanning the code with an Ant Task, applying a set of metrics, and generating an HTML or XML report of the results.

This version comes with a SingleSeriesHtmlReportWriter for creating HTML reports for a single series of metric values, and can now filter metric values included within the reports by metric name, level and function.
