Sigil is an eclipse plugin that helps developers build and test code to be deployed on the Newton platform

Features:

• New (Newton Project, Composite, System)
• Syntax highlighting and code completion for SCA/System docs
• Launch Newton in Debug/Standard vm from Eclipse
• Full debug support - break points/source code/step through etc
• Install Composites into running newton from Eclipse
• Log integration
• Ability to manage bundle definition/interrelations

Other stuff on the horizon is:

• Hyperlinks (link between elements in SCA docs to source code etc)
• Richer composite management (gui view, list, uninstall etc)

According to wikipedia:

A sigil (pronounced /'sɪdʒ.ɪl/ or /'sɪg.ɪl/; pl. sigila or sigils) is a symbol created for a specific magical purpose. A sigil is usually made up of a complex combination of several specific symbols or geometric figures each with a specific meaning or intent.
