NAME
    Cache::FileBackend -- a filesystem based persistence mechanism

DESCRIPTION
    The FileBackend class is used to persist data to the filesystem

SYNOPSIS
      my $backend = new Cache::FileBackend( '/tmp/FileCache', 3, 000 );

      See Cache::Backend for the usage synopsis.

      $backend->store( 'namespace', 'foo', 'bar' );

      my $bar = $backend->restore( 'namespace', 'foo' );

      my $size_of_bar = $backend->get_size( 'namespace', 'foo' );

      foreach my $key ( $backend->get_keys( 'namespace' ) )
      {
        $backend->delete_key( 'namespace', $key );
      }

      foreach my $namespace ( $backend->get_namespaces( ) )
      {
        $backend->delete_namespace( $namespace );
      }

    new( $root, $depth, $directory_umask )
        Construct a new FileBackend that writes data to the *$root*
