Suppose you have an interpreter that takes command line arguments including the filenames for a script to be run, and optionally further arguments to be passed to the script. The interpreter then needs to figure out which of the given arguments were intended for its own use and which were intended to be passed to the script.
Is there a widely used convention for separating the former from the latter?
