=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.
