| Mode of operation: | |
| Each of the *.in files is XER-decoded, then converted into PER, | |
| then compared with the .out file, then decoded back into XER | |
| and compared to the original .in file content. | |
| Naming conventions: | |
| *-C.in - Comparison of .out might fail, but decoding succeeds | |
| *-P.in - PER decoding of .out file must fail. | |
| *-X.in - Final XER comparison must fail. | |
