Re: [Quantlib-users] regarding permission

[Francois B. <ig...@gm...>]

Hi

I'm also interested this question. Hope it's OK if I add to it, Mudit.

I understand that the license is quite permissive, but I'm still not sure
exactly what it requires.

Can I link to quantlib from a commercial product?

Can I copy code directly from quantlib into my project and compile it?

When do I have to release the quantlib source code alongside my commercial
product?

I know few of us here are lawyers and that the usual disclaimer holds, but
I'm sure someone else here is less confused than I am.

While we're at it, it doesn't pertain to quantlib, but how do the answers
to my questions change if the license were eg a GPL based license?

Thanks
Francois
