=head1 NAME

DirHandle - supply object methods for directory handles

=head1 SYNOPSIS

use DirHandle;
    $d = DirHandle->new(".");
    if (defined $d) {
        while (defined($_ = $d->read)) { something($_); }
        $d->rewind;
        while (defined($_ = $d->read)) { something_else($_); }
        undef $d;
    }

=head1 DESCRIPTION

The C<DirHandle> method provide an alternative interface to the
opendir(), closedir(), readdir(), and rewinddir() functions.

The only objective benefit to using C<DirHandle> is that it avoids
namespace pollution by creating globs to hold directory handles.
