The system is designed to be integrated and can be easily
configured by developers or designers in a couple of steps. The
interface encapsulates and presents within windows (of unlimited
number) any inner SVGs, that will be directly embedded in the SVG
file, or linked SVG documents. The package contains detailed
configuration and installation instructions.
