The projects in this folder are special extension to Minimal-J. They may be incomplete or their code is not as clean as the core of Minimal-J. I simply don’t have the resources to keep everything in a perfect state. Still these projects may be useful or provide a hint of what is possible with Minimal-J.

The ext projets are not released to a maven repository and don’t have a release management yet.
