+This test checks that when JBMC is given a JAR file whose manifest specifies a
+main class, we can ignore this main class and instead load all classes of the
+JAR file with the option --ignore-manifest-main-class.
+Without this option, IrrelevantClass would not be loaded as it is not reachable
+from RelevantClass (the main class).
