+ * 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.
