GPL requirements and emacs modules

[mike . rosset]

Hello,

I was wondering what the GPL requirements are for dynamic modules are. I
know that the module needs to export plugin_is_GPL_compatible.

For example I have written a guide, on how to write emacs modules in
the go programming language. The guide can be found here
https://mrosset.github.io/emacs-module/ . I would like to update the
guide to include what is required in order to make the module GPL
compatible.

If anyone could give me some insight as to what being GPL compatible
means. Would be appreciated.

Regards,

Mike Rosset
