Current architecture (updated April 2009)

• Language: C# 3.0, with .Net 2.0 SP1 on Windows and mono on Linux.
• GUI: Windows Forms (we found GTK# to be tough going), using only classes currently available in mono.
• Rendering: Pango on Linux, MultiScribe (Graphite) on Windows
• Backend: LIFT xml files
• Dependency injection using Autofac
