Licences

Some of the obvious questions about the circumstances in which you do and do not need a Licence for YAFFS

YAFFS is, and will remain, a free-software project. That's why it is licensed under the GPL, to ensure it remains free. However, we also want to make YAFFS available to as many people as possible, and some people who wanted to use it found that they couldn't if it was GPLed. Consideration of the best way to take YAFFS forward has resulted in a dual-licensing scheme, similar to that used by MySQL AB and others. Here we explain how the various components are licensed and our reasoning for doing it this way.

While the YAFFS code is available free of charge under GPL, that entails the obligation to disclose Source Code for your application using YAFFS. An Aleph One Licence does not impose that obligation and so is attractive for proprietary projects.
