module test_astbuilder

nitc :: test_astbuilder

Program used to test the clone method of the astbuilder tool

Program use the nit interpreter to do his job. It take a nit file into parameter and replace the ast nodes by a clone. After replace it run a basic interpretation. When a new method clone is implemented you need to add a redefinition to test it. When the number of method clone will increase its more practical to define the nodes to not clone.
