45 /* Survey of C# compilers.
53 We try the CIL interpreters in the following order:
54 1. "cscc", because it is a completely free system.
55 2. "mcs", because it is a free system but doesn't integrate so well
56 with Unix. (Command line options start with / instead of -. Errors go
57 to stdout instead of stderr. Source references are printed as
58 "file(lineno)" instead of "file:lineno:".)
59 3. "csc", although it is not free, because it is a kind of "reference
60 implementation" of C#.
61 But the order can be changed through the --enable-csharp configuration
