NAME
       Cache::FileBackend -- a filesystem based persistance 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 );
         }

METHODS
       See Cache::Backend for the API documentation.

       new( $root, $depth, $directory_umask )
           Construct a new FileBackend that writes data to the $root directory, automatically
           creates subdirectories $depth levels deep, and uses the umask of $directory_umask when
           creating directories.

PROPERTIES
       (get|set)_root
           The location of the parent directory in which to store the files

       (get|set)_depth
