NAME

Hub::Data::HashFile - Flat file data which supports nested perl structures.

Part of the Hub Library

SYNOPSIS

use Hub;
my $hf = Hub::mkinst('HashFile','myfile.hf');

$hf->set( "eye_color", "green" );   # set a simple property
$hf->save();                        # saves the file to disk

DESCRIPTION
