FRIEND PROJECTS

1. The jBPT Library (https://github.com/jbpt/codebase) provides many useful functionalities to the PQL tool.
2. Apromore process model repository (https://github.com/apromore/ApromoreCode) integrates the PQL tool, refer to the custom installation instructions in the README file of the Apromore project. A screencast on using PQL in Apromore is available here: https://www.youtube.com/watch?v=S_U6frTWd3M.
