@normanp:
Maybe it's a good time to teach your student about how to involve in open source project and become the part of the community. Unlike if they're using a closed and commercial product which they would receive a professional document and support, it's not the case when they're using an open source project that build by the community, especially if the project sets the focus more on technical things (new features, bug fixing, stabilizing, etc) as Lazarus.
Since Lazarus and Delphi share many things in common, your students may start the contribution to this project by studying Delphi documentation first. As soon as they understand them, they can help to complete documentation of this project. This way, those students don't only learn how to use a product, but also how to participate in a project, especially in an open source project. A few years since now, this project would have more supports from students like them. It's good for them and this project as well.
What do you think?
