BY-SA has less restrictions than the GPL: Any GPL work can only be incorporated into other GPL works. On the other hand, BY-SA can be incorporated into a other works so long as the BY-SA part is satisfied. >> I looked at other by-sa licenses (particularly MPL, CDDL, CPL, EPL) >> but found them to be lengthy.

Please don't do it. You are correct. However, I find the licenses I have examined so far don't really suit my ethical beliefs or could be made simpler. So I'm going to go through the entire OSI approval process (which requires examination of existing licenses and convincing them why I need to make my own). Hopefully, I will find an *existing* license that suits my needs in the process. If not, at least I will have more knowledge of this licensing stuff by the end. > This might also be of interest: > http://www.dwheeler.com/essays/gpl-compatible.html Thanks for the article. I will make sure that my license is GPL compatible. On a side note: Personally, I don't really care for the license proliferation argument. Proponents are afraid that too many licenses will confuse developers and cause incompatible licenses. To me, this sounds like saying "we have too many window managers (WMs), and some are even incompatible with each other! So stop making new WMs just to try new ideas..." All WMs adhere to the X Windows API, otherwise we wouldn't be able to use them on our *NIX systems. In this manner, the X Windows API is like the DFSG -- providing a common ground for the licenses to be considered as free software. Beyond this level of cohesion, the choice of WM should be up to me... I don't use a WM just because it is the most popular (e.g. I use wmii instead of GNOME or KDE because it makes sense to me). Likewise, the choice of license should be up to the developer, based on their ethical beliefs or other needs. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble?
