Edje is a complex graphical design & layout library.
-It doesn't pretend to do containing and regular layout like a widget
+It doesn't intend to do containing and regular layout like a widget
set, but it is the base for such components. Based on the requirements
of Enlightenment 0.17, Edje should serve all the purposes of creating
visual elements (borders of windows, buttons, scrollbars, etc.) and
canvas and set the bundle file to use, specifying the @b group name to
use. Edje will load such information and create all the required
children objects with the specified properties as defined in each @b
-part of the given group. See the following annotated example:
