Trusster Open Source License

Hi,

Could you please clarify if the Trusster [1] Open Source License is an
acceptable Free/Open Source Software License for the Fedora project.
The Teal [2] project uses this license:

Can you please let me know what is meant here by "GPL incompatible",
or what is not possible when using TOSL?

I have been able to package the Teal tool (released under TOSL) for
Fedora. It provides a framework for verification of source code.
Hence, test suites written using this framework also have to "include"
project source code files. Please CMIIW:

1. If the project source code is released under GPL and the test
suites use TOSL, can we still use them with Teal?

2. What if the project source code is released under LGPLv2+, can we
still use Teal as long as the test suites are also released under
TOSL?

Please clarify,

Thanks!

Hi,

I checked with the TOSL authors from Trusster, and here is their reply:

=== QUOTE ===

Yes, our license is the SleepyCat one...

Nope. Any project a customer does is totally owned by them in whatever
license they want.

Yes.

    I see that in the examples you "include" the RTL sources, but, does
    that involve compilation between TOSL framework code and RTL LGPLV2+
    code?

Yes.

The idea behind TOSL was to encourage others to use it, but not
require that their work be in open source.

=== END ===

So, if I ship examples that use GPLv2+ or LGPLv2+, can I use the
following in License at teal.spec?

  License:     TOSL and (GPLv2+ and LGPLv2+)

Do let me know your views. Thanks!

It means that you cannot take a library which is under TOSL and combine
it with files under the GPL, as the result is incompatible.

Assuming the files are combined as you describe, the answer is no.

LGPLv2+ is generally considered to be compatible with most licenses, I
doubt there is any problem with this combination.

Upstream is now willing to release their software, Teal, with a
LGPLv2+ license. They want to know if them sending an e-mail is
sufficient for us to package the same for Fedora, or anything else is
required?

I suggested that it will good if they could mention and include the
LGPLv2+ license information in the source code.

Any thoughts?

Nope, that's fine. Just include a copy of the email where they give
permission for use under the LGPLv2+ terms as a Source file in the Teal
package, and include it as %doc.

If they do this, you do not need to include their email in the package.

Upstream has provided the same, and I have the package up for review at:

Thanks for your help!
