| 49 We try the CIL interpreters in the following order: | |

| 51 2. "mcs", because it is a free system but doesn't integrate so well | |
| 52 with Unix. (Command line options start with / instead of -. Errors go | |
| 53 to stdout instead of stderr. Source references are printed as | |
| 54 "file(lineno)" instead of "file:lineno:".) | |
| 55 3. "csc", although it is not free, because it is a kind of "reference | |
| 56 implementation" of C#. | |
| 57 But the order can be changed through the --enable-csharp configuration | |
| 58 option. | |
