The custom license indicate 2 extra licenses that I can't find information about in the spdx.org list.

those are: Tk and Tix part in pTk folder of the source tree.

The license files can be found in source tree:

pTk/license.terms for details of this Tk license
pTk/Tix.license for the Tix license

@ikey I hope you or someone in Triage Team can help with sorting out the license part.

Isn't it the TCL license : https://spdx.org/licenses/TCL.html

I was thinking of it and its the best fit, but I feel we need to go with what is included in the project.

Besides I have looked different distros: Arch, Debian and openSUSE and all of them seems to write different Licence info for this package. This does not make it easier :)

Links below to the different licenses for this package.

@ikey can you please review licenses and let me know what "custom" license in package.yaml should be.

https://github.com/eserte/perl-tk/blob/master/pTk/license.terms
https://github.com/eserte/perl-tk/blob/master/pTk/Tix.license

@ikey I know you have been busy, but do you have any time to look at the license issue for this?

Thanks!
