For the Developer

Modular code design
Programming language: C (standard compiler for porting)
Uses GTK+ for UI ( the glade tool has been helpful)
extensible access method architecture, access methods are described in XML (saved as .xam files)
static (pre-made) keyboards are described in XML (saved as .kbd file)
makes use of the at-spi orb (part of GAP gnome accessibility project), for creating dynamic keyboards (e.g. menus, tool bar buttons)
