Gtef (GTK+ text editor framework) has been renamed to Tepl (Text editor product line). The end of Tepl is pronounced like in “apple”.
I didn’t really like the name Gtef. And since the project is still young, it was easy to rename everything.
I’ve also written a more complete introduction.
The name “Text editor product line” was inspired by this book: Feature-Oriented Software Product Lines. It’s an interesting book, I’m learning new things, like the difference between a white-box framework and a black-box framework, or cross-cutting concerns (and how to better handle them), etc.
