File::Listing - parse directory listing

=head1 SYNOPSIS

 use File::Listing qw(parse_dir);
 $ENV{LANG} = "C";  # dates in non-English locales not supported
 for (parse_dir(`ls -l`)) {
     ($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');

=head1 DESCRIPTION

This module 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'.  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
directory 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
