File::Listing exports a single function called parse_dir(), which can be used
 to parse directory listings.
 .
 The first parameter to parse_dir() is the directory listing to parse. It can
 be a scalar, a reference to an array of directory lines or a glob
 representing a filehandle to read the directory listing from.
 .
 The second parameter is the time zone to use when parsing time stamps in the
 listing. If this value is undefined, then the local time zone is assumed.
 .
 The third parameter is the type of listing to assume. Currently supported
 formats are 'unix', 'apache' and 'dosftp'. The default value 'unix'.
