[Sglib-general] questions about the license

[jianghu <jia...@gm...>]

Hi all,

I am interested in sglib and planning to use the code in my project, but now
I am confused about the license declaration. Below part is copied out from
sglib.h

  License Conditions: You can use a verbatim copy (including this
  copyright notice) of sglib freely in any project, commercial or not.
  You can also use derivative forms freely under terms of Open Source
  Software license or under terms of GNU Public License.  If you need
  to use a derivative form in a commercial project, or you need sglib
  under any other license conditions, contact the author.

It seems that the sglib can be used freely, just like BSD license, from the
sentence "freely in any project, commercial or not" and the sentence
"Basically,
I only care that you do not remove the Copyright notice from the source code
when using Sglib." from the website. But from the later part it seems for
non-commercial project only, "If you need to use a derivative form in a
commercial project, contact the author".

Any one can clarify it for me? I am in a commercial project and found the
sglib is perfect. The whole project will be commercial and non open source
except for some necessary header files. The sglib source code, i.e. sglib.h,
will not be modified. If a bug of it should be fixed, I will contact the
author. But some helper functions or wrappers will be written based on sglib
source code.

Thanks for your response!

Regards,

Jianghu
