The File::Spec family of modules lets you construct paths using directories and filenames without hardcoding platform-specific directory separators. Supported systems include Unix, VMS, Mac, and Win32. These modules all offer a catfile class method that catenates together each path component using the specified platform's path separator. The File::Spec module returns different results depending on your current platform. The others return results specific to that platform. The File::Spec::Functions module provides a functional interface.
