• complete sourcecode FREE available
• entirely coded in win32 asm (MASM32v8)

• and much more...

Project Status

On August 2009 the decision was made to make EIS open source because I do not have enough time to maintain it.

So if you like it, use it. And if you can contribute something - don't hesitate!
