 This is all getting quite complex, so in summary:
 
 * Snakemake loads the `--configfile` supplied on the command line, or else defaults to the one named in the Snakefile, or else
   runs with no config file.
 * Individual `--config` items on the command line always take precedence over settings in the config file.
-* You can set multiple `--config` values on the command line and you always need to put `--` to end the list.
+* You can set multiple `--config` values on the command line and the list ends when there is another parameter, in this case `-p`.
 * Use the `config.get("item_name", "default_val")` syntax to supply a default value which takes lowest precedence.
 * Use `config["item_name"]` syntax to have a mandatory configuration option.
