Thank you very much @PeterDaveHello for this contribution.
We require copyright assignment for any contribution to the SDK, and license the integrated work under the BSD-3 license of the SDK.

Do you agree to this?

Please also note that we will keep this latest branch around as the default for this repo for a while, but that:

• The next Debian package release will be based on what is currently the master branch, with some commits resolving issues (and possibly including this adding zh_TW translation) integrated there
• We're also revamping the Ecere SDK into a more modular / less monolithic set of libraries which are in separate repos ( https://github.com/ecere/eC , https://github.com/ecere/gfx , https://github.com/ecere/wpal , ... ), and this repo may eventually become a meta-repo that brings all of these components together as git sub-modules. We would try to integrate your zh_TW translation there as well.

I am curious if you are actually using the Ecere SDK for any of your projects? I'm always happy to exchange with users and welcoming contributions.

Thanks again!

Cheers,

-Jerome

No problem, agreed. I'm exploring at this moment!
