Path rules for include unclear

[twothe]

As a new user of HTL I am trying to understand where my files need to be placed and how they can be accessed with an include directive. While the spec describes how to actually include things, it does not explain to a beginner in an understandable way how the path to it must be formed correctly to actually be able to include a specific file.

The same problem exists for the other ways to include things, like use, or resource.

Does 7264a84 help with this, or do you think something more would be required?
