This is a BSD license , one of the most business friendly licenses.
Here is an excerpt from an article written by Stephen Fishman :
(...) the Berkeley Software Distribution (BSD) License. One of the earliest nonproprietary licenses, it permits users to do virtually anything they want with BSD-licensed code: they may distribute the software - either for free or commercially - without providing the source code; they also may modify it and distribute the changes without providing the source code. Anyone can turn software distributed under no-copyleft licenses into proprietary software (and then relicense it for a fee) as long as they credit the developers of the original open source software.
Rools is not licensed under the GPL or the LGPL. It’s licensed under the BSD license, which is way more business-friendly than the GPL or the LGPL. And it’s BSD licensed since the day 0.
