Sugar is built in python with a variety of open source packages. Programing in the sugar environment requires a basic understanding of both the Sugar User Interface, supporting third party packages, and built in sugar packages.

Traditional software packages are built against Application Program Intefaces. Sugar runs Activities instead of applications, but from a developers point of view, it's the same thing.

Third Party Packages

• Abiword
• Avahi
• GTK - GNOME Toolkit
• Cairo
• D-BUS
• Evince
• Hippo

• Avahi - Network Discovery Service
• Matchbox - Graphical Windows Manager
• Xul - XML User Interface Language (aka gecko and other identity challenged projects)
• Pango - GTK package for text rendering
• ATK - GNOME Accesibility Toolkit
• gstreamer - media player
• X windows - the tried and true ancient X11 display libraries (Shoulders on which much else stands).
