You can find Proparse pre-built libraries on Joanju's Proparse page at
joanju.com/proparse/.
The prorefactor/configure.p script is now included in the Proparse .zip file distributions, but see Project Config. Dump for a description of how to use it to get started.
Copy resources.example/testparse.properties to the top directory, and edit it for your own project. Then:
java -cp proparse.jar proparse.TestParse
Example usage:
java -cp proparse.jar proparse.TreePrint unittest data/newsyntax/101b/Test2.cls
