There are some interesting features available with each module. We won't use it in our module, but it is still something interesting to know.
You just have to set the ps_versions_compliancy variable in your constructor with PrestaShop's minimum (and maximum) version needed to make the module work:
$this->ps_versions_compliancy = array('min' => '1.5.2', 'max' => '1.6.0.7');The previous line means that your module works with PrestaShop 1.5.2 and further versions until PrestaShop 1.6.0.7.
If you try to install a module that contains the previous line on PrestaShop 1.5.1, your module won't install and an error message will be displayed.
