*the shell* expands your unquoted wildcards before passing the args to your program.

> Example: If a directory has two files m1.txt and m2.txt, and my ocaml program (here called myprog) is invoked with wildcards it would behave something like this:
> Example call         Command line arg within my program
> ./myprog m*       -> Sys.argv.(1) = "m1.txt"
> ./myprog m?.txt   -> Sys.argv.(1) = "m1.txt"
> ./myprog "m*"     -> Sys.argv.(1) = "m*"

You will have :
 ./myprog m*       -> Sys.argv.(1) = "m1.txt" and Sys.argv.(2) = "m2.txt"
 ./myprog m?.txt   -> Sys.argv.(1) = "m1.txt" and Sys.argv.(2) = "m2.txt"
 ./myprog "m*"     -> Sys.argv.(1) = "m*" since the * is inside quotes
