	// working directory, with the given name.
	//
	// The name is subject to strict validation, any deviation from the
	// rules will end in an InputError:

	//	- no directory traversal.
	// Additional rules may be imposed by the underlying file system.

	//	  a main input file.
	// If in any step only one candidate is found, this return its name,
	// and an error otherwise.
	MainInput() (string, error)
