-// When passing the string, make sure it includes the program name as the first

-// A "switch" is an argument preceded by "/".  Each switch can take 0..n
-// arguments.
-// Example:  foo.exe /sw a "b b" /sw2 /sw3
-// * foo.exe is the program name
-// * sw, sw2, and sw3 are switches.
-// * a and 'b b' (without the quotes) are the arguments to the sw switch.
-// * sw has 2 arguments and sw2 and sw3 have no arguments.
