So what I'm planning to do is to create a script which one part calls (via Python's subprocess) external open source script licensed under GPL-2.  To make it easier for users I'd like to distribute the GPL-2'ed script with with my own so that call could be easily done on the correct version of software. (I want to use the specific version of it). Does this scenario affect the license of my script? I'm slightly confused as I'm not using any code of it, my script just wants to call the open source script in order to perform one step. If this was denied would it change a situation if my script tried to download the open source script during the execution? (So it wouldn't be distributed with mine)
