You have these choices (you can look them all up in the docs for more info):
current-command-line-arguments— a vector holding the command line argumentsYou can start a script with the
-mflag, which will require the file and look for a providedmainfunction, then apply it on the command-line arguments (as a list of strings)Or you can require
racket/cmdlinewhich provides a macro that can be used to define several flags in a convenient way.
