    # expected to hit the first slide class and then abort evaling
    # the config file. This is necessary so we can have the options at the
    # beginning of the config file while they are needed in the tamplates
    # for instance. So what happens is:
    # 1. read config (options should be on top)
    # 2. error upon encountering the first class, continue in initialize
    # 3. Load slides and templates (while options are already loaded)
    # 4. eval the config file again (options are read again, shouldn't be
    #   a problem). This time no error as slide and template classes are
    #   loaded
    # Yes there could be a separate options file, but it didn't feel right
    # to have a config and an options file
