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.
