-===== Computing Metrics ===== 
- 
-Computing POM metrics using PADL is made easy by the helper class ''​pom.helper.MetricsGenerator''​. After having installed CPL, PADL, and POM, just go into the ''​POM Tests''​ project and have a look at this class. It provides a main method with snippets of code to call one of the three methods: 
-   * ''​computeMetricsFromDirectory''​ 
-   * ''​computeMetricsFromEclipse''​ 
-   * ''​computeMetricsFromJARs''​ 
-which can be used to compute automatically metrics from various input sources. Also have a look at the constant array listing the metrics that must be computed or avoided: ''​METRICS_TO_AVOID''​ and ''​METRICS_TO_COMPUTE''​.
