I have a project which use an external library hosted on GitHub. The external library is mine, but it needs to have an own repo because I use it in several projects. This library has the source code I need and a little demo in it. How can I do if I want to add as a submodule only the source code without the rest of the project (such as the demo files)? Is it possible? What is the best solution?

The two parts could also be separated as project - sub-project(submodule), such that you can take which ever part you need.
It will depend on your viewpoint as to whether the examples are a sub-project (submodule) of the library, which only need to be populated when required.
Or the examples should have the library as a sub-project (submodule) so as to demonstrate how it's done.
The latter choice is more logical, but you end up with a circular reference within the library's README file where it points to the example project, which includes itself!

The first solution you propose is interesting, but I should have 2 repos for the library in that way, right? One for the library itself, another for the demo project. And if I want to make the code open source, the users have to download two different projects, right? – Andrea Mario Lufino Aug 04 '13 at 11:34

Yes, it would be two repos, with users able to either select the raw library repo, or select the example repo (which would have the library as a sub-module, so would be fetched separately with one of the `submodule update` variants) – Philip Oakley Aug 04 '13 at 18:51
