Guiliani:Features
From Guiliani
Guiliani is a C++ software framework enabling the creation of visually appealing, hardware and OS platform-independent GUIs for embedded systems.
Guiliani adopts the philosophy of write once, compile for & run on many different target hardware. Once a Guiliani application has been developed, it can run natively on supported target platforms. When using Guiliani, the usual development workflow is to design the application on a PC and target a set of embedded platforms for production release.

Architecture overview
Guiliani is split into two layers, the Guiliani runtime engine, and a platform abstraction layer.
