+The tools generate for each libfirm header file a Java class
+containing native method calls and static fields. The native methods
+are derived from the methods in the corresponding libfirm header. The
+method names are generated by replacing all occurences of '_x' by 'X'.
+(The libfirm headers may not contain method names that only differ by
+capitalizing the letter after an underscore.) The static fields are
+derived from the enumerators in libfirm.
