Copyright

Yabasic may be copied, at your choice, under the terms of either the Artistic License or the GNU General Public License (GPL).

Earlier versions of yabasic have been subject to the GPL alone and it is kept for backward compatibility. Since version 2.60 you have the choice to use yabasic under the terms of the Artistic License, which gives you the right to use and distribute yabasic in a more-or-less customary fashion, plus the right to make reasonable modifications, while giving the original author some semblance of artistic control over the development of yabasic.

Regardless which license you choose (GPL or Artistic) for yabasic, it does not apply to your own yabasic-programs. The programs you write are your own work and you may use any license you like.

Finally some examples of what is possible under the terms of the Artistic License:

• Put yabasic on your own webpage, CD or other medium, charge for the service of distibuting yabasic.
• Write your own yabasic-programs, put yabasic itself into the package and sell the whole thing. "Sell" is more than charging for distribution costs and time: You may make real profit with your own programs.
• Modify yabasic, add or remove features and capabilities, sell the modified version.

If you are still in doubt, please check out the licenses above.
