Many hundreds of hours work has gone into the development of Xanjax. The license I have chosen will ensure that the public version of Xanjax remains free for everyone to use and modify for all time.
None of the license is intended to prevent you from using Xanjax to make a profit. Obviously the licence doesn't permit anyone except the original copyright holder to derive commercial software from Xanjax, or to otherwise gain profit or status by mis-representation. There are few other restrictions however. If you can use Xanjax to build a profitable website, you are most welcome to do so.
Unfortunately, some not so nice individuals in the world think nothing of stealing other people's hard work to use as their own, either for undue profit or for unearned status. Parts of the license that perhaps sound a bit harsh, are mainly for them.
Finally, the license encourages (but does not enforce) people making changes to Xanjax to offer them for inclusion in the official free version. Note however that the Xanjax project is never under any obligation to include contributed works in official Xanjax releases and that if you ever change Xanjax code in any way, even if the changes are not included in the official release, you must still make those changes publically available using the same free licence under which you received Xanjax.
I hope that you will enjoy using Xanjax and profit from its use. I also hope that you will repsect at all times the license, and my personal copyright and trademarks in Xanjax. I have given Xanjax to the world for the greater good, but it would also be nice if all my hard work helps feed my family (and me) in some way.
Thanks for taking the time to respect the Xanjax license.
