This is some documentation for the High-level Universal GUI (HUG).

HUG was created to provide elementary access to GTK widgets without needing
a lot of code in a client script to achieve this. With HUG it is possible
to create userinterfaces and also to have access to graphical functions. 

For GTK3, the macro prefix has changed to "m_".
