Hi. I'm planning to use OSERL in a commercial project, so I'm interested in it's license.
The plan is to write custom software our client requests and sell it to him as a closed source solution. As far as it concerns my company, only our source closeness matters, we can include open-source libraries' sources without problem as far as our source remains closed.
So what's the license of OSERL? Is the scenario I've described possible?
