Supporting the Open Source Community
The code underlying IFs is open source to support educational use and the development of the next generation of analysts. You are welcome to develop your own modules and subsystems for use with the IFs system.
Free open-source software is not free to develop or maintain, of course. We hope that if you find IFs useful you will credit and provide feedback to the Pardee Center.
