 ## Difference with the original version of the plugin
 
 In this version, the core of the plugin is based on [SRCML](http://www.srcml.org/). In essence, the source-code of the project is encoded in an XML file. This XML file is then processed via XPath queries for different rules. The main XML file is a variable in the plugin code and is not accessible out of it. However, the temporary process results are written in files in the project folder. Removing these files are safe.
