The licence gives right for unlimited usage within a single company. It also provides free access to updates, limited to the same major version (for example : a licence for version 2.0.0 will allow product usage in all 2.x versions, but will no longer be valid for 3.x). It comes in the form of a text file to integrate in the application CLASS_PATH, directly or packaged in a JAR file.
To test the suitability of MRules for your needs, you can get a free trial license, with access to all features. The defaut trial period is one month, but it can be extended by a simple mail request.
For more informations, please read the entire End User License Agreement (EULA).
