[speex-dev] Confusion over xiph.org license

[Tyler Knott]

I'm no expert but I think I know how this would work.

>Under the Xiph.org license, it states:
>"Redistributions in binary form must reproduce the
>above copyright notice, this list of conditions and
>the following disclaimer in the documentation and/or
>other materials provided with the distribution."

>Does my use of Speex qualify as "redistribution in

Yes.

>The reason I ask is because I do NOT
>want to include "Redistribution and use in source and
>binary forms, with or without modification, are
>permitted" in my license/documentation because my
>program does NOT allow modification and in some cases
>does NOT allow redistribution (the post-paying version

You don't have to put that in.  You just need to put in the copyright 
notice.  That phrase of the Xiph.org license just means that you have 
permission to use/redistribute the Xiph.org implimentation of Speex(in 
binary and/or source form) without any restrictions.

Be sure you specify that it is Speex that has that copyright and not the 
main program.  If you'd like to know more about open-source licenses(and 
open-source in general) then I'd reccomend looking at 
http://www.gnu.org/licenses/licenses.html or
