 	- `git_error **error_ptr`: the pointer where the error will be created.
-	- `int error_class`: the class for the error. This is **not** an error code: this is an speficic enum that specifies the error family. The point is to map these families 1-1 with Exception types on higher level languages (e.g. GitRepositoryException)

 - Use short, direct and objective messages. **One line, max**. libgit2 is a low level library: think that all the messages reported will be thrown as Ruby or Python exceptions. Think how long are common exception messages in those languages.
