The GDOv7 application framework uses itself to install.
The bootstrap process:
@include protected/config.php
require GDO7.php
Application::init();
That's it. GDO is useable.
Of course GDOv7 is humble. It does not do anything when bootstrapped.
Try to enable the logger, debugger and render something.
Debug::init(true, true) # init debugger with die and mail.
Logger::init('testuser', 0xffffffff); # all log levels
GDT_String::make()->initial("Hello world")->render();
