Once this is in place, you can call $this->backward and $this->backward_error in your module in order to pinpoint 1.5- or 1.4-specific code:
| Code Block |

public function install()
{
if (!$this->backward && _PS_VERSION_ < 1.5)
{
echo '<div class="error">'.Tools::safeOutput($this->backward_error)>l('In order to work properly in PrestaShop v1.4, the Test module requires the Backward Compatibility module 0.3+.')).'</div>';
return false;
}
