NAME
       File::Listing - parse directory listing

SYNOPSIS
        use File::Listing qw(parse_dir);
        for (parse_dir(`ls -l`)) {
            ($name, $type, $size, $mtime, $mode) = @$_;
            next if $type ne 'f'; # plain file
            #...
        }

        # directory listing can also be read from a file
        open(LISTING, "zcat ls-lR.gz|");
        $dir = parse_dir(\*LISTING, '+0000');

DESCRIPTION
       This module exports a single function called parse_dir(), which can be
       used to parse directory listings. Currently it only understand Unix 'ls
       -l' and 'ls -lR' format.  It should eventually be able to most things
       you might get back from a ftp server file listing (LIST command), i.e.
       VMS listings, NT listings, DOS 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.  The values will
       be strings like 'unix', 'vms', 'dos'.  Currently only 'unix' is imple-
       mented and this is also the default value.  Ideally, the listing type
       should be determined automatically.

       The fourth parameter specifies how unparseable lines should be treated.
       Values can be 'ignore', 'warn' or a code reference.  Warn means that
       the perl warn() function will be called.  If a code reference is
       passed, then this routine will be called and the return value from it
       will be incorporated in the listing.  The default is 'ignore'.

       Only the first parameter is mandatory.

       The return value from parse_dir() is a list of directory entries.  In a
       scalar context the return value is a reference to the list.  The direc-
       tory entries are represented by an array consisting of [ $filename,
       $filetype, $filesize, $filetime, $filemode ].  The $filetype value is
       one of the letters 'f', 'd', 'l' or '?'.  The $filetime value is the
       seconds since Jan 1, 1970.  The $filemode is a bitmask like the mode
       returned by stat().
