Recently, XML has achieved the leading role among languages for data representation and, thus, the amount of related technologies and applications exploiting them grows fast. However, only a small percentage of applications is static and remains unchanged since its first deployment. Most of the applications change with newly coming user requirements and changing environment. In this paper, the authors describe a tool for evolution and change propagation of XML applications called eXolutio, which has been developed and improved in their research group during last few years. The text should help the reader to get acquainted with the tool and its theoretical background.
