// is populated with a textual description of an appropriate
// reason.

// (if not set already). This is a *relative* path, that will be used to
// search from the application's InstallationDirectory
// (see vtkKWApplication::InstallationDirectory) and the UserDataDirectory/
// It can include a subdirector (still relative).
