- Files runnable as Java application and JUnit test for each session can be found in package de.uni_koeln.phil_fak.iv.tm.pX.PraxisX.java (X for the session number)
- To run all tests: run All.java as JUnit test (needs corpora in data/, run All.java as Java application to generate)
- The Ant script can compile and deploy the code as an executable Jar (ant deploy), generate Javadoc (ant doc) and run tests (ant test), which are summarized in an HTML report (ant report)
