For instance, hyphens are often used as part of executable names on Linux, but if I do this:$ dmd usage-printer.d I get the following error:usage-printer.d: Error: module usage-printer has non-identifier characters in filename, use module declaration instead
Try adding the line:
module usage_printer;
at the top of the file. This overrides the default module name
(same as file name).
