Because we think native language support is a very important aspect of making a user interface more easy to understand we prepared Trinc-Prolog to support multiple languages. For now we support English and Dutch. In the future we plan to support French, German and Spanish. As you may have noticed the amount of documentation is huge. We started the translation of the documentation to Dutch but we decided to stop this project for now.
Translation currently requires to much of our resources.
In the future we hope to support the major languages of the world. Trinc-Prolog has built in support for developing applications for multiple languages. Each time we release a commercial version we will release a corresponding trial version. In this way you can use Trinc-Prolog to teach your students the Prolog language. So from this day it is allowed to use the Trinc-Prolog trial version for teaching Prolog to your students Some people have indicate that they like to have a some kind of university license which is less restrictive than the use of the trial version.
