+# Exercise 1
+# 1. Getting help with -help or -h.
+# 2. A least three arguments that are flags, meaning they don’t take an extra
+#    argument but simply putting them on the command line turns something on.
+# 3. At least three arguments that are options, meaning they do take an
+#    argument and set a variable in your script to that option.
+# 4. Additional “positional” arguments, which are lists of files at the end of
+#    all the – style arguments and can handle Terminal wildcards like */.txt.
