This is less than what google or sun does. However, GAP does nothing like this. On the other hand, GAP is organized around modules (often single-authored and sometimes with non-GPL'd licenses), with a small number of people contributing to the kernel. I don't think Maxima does this either. But as

Hi there, what is the practice w.r.t. this kind of stuff in other big open-source software projects? Quite honestly, I find it rather worrying that so much legal stuff is suddenly involved in writing a simple patch. If at all possible I would love to avoid this. Martin -- name: Martin Albr

I know of no code which in Sage which is GPLv2 only. William or Michael, please correct me if I am wrong. I think that code which is GPLv2 (only) is not GPLv2+ compatible, since GPL2+ says the modifications can be released under either GPL2 or GPL3 (at your choice). "GPLv2 only" restricts that ch
