* PRADO Requirements Checker script
*
* This script will check if your system meets the requirements for running PRADO.
* It will check if you are running the right version of PHP, if you included
* the right libraries and if your php.ini file settings are correct.
*
* This script is capable of displaying localized messages.
* All messages are stored in messages.txt. A localized message file is named as
* messsages-<language code>.txt, and it will be used when the client browser
* chooses the corresponding language.
* The script output uses a template named template.html.
* Its localized version is stored in template-<language code>.html.
