// Class used to create and/or parse command line arguments. Arguments with
// '--', '-' and, on Windows, '/' prefixes are considered switches. Switches
// will always precede any arguments without switch prefixes. Switches can
// optionally have a value specified using the '=' delimiter (e.g.
// "-switch=value"). An argument of "--" will terminate switch parsing with all
// subsequent tokens, regardless of prefix, being interpreted as non-switch
// arguments. Switch names are considered case-insensitive. This class can be
// used before CefInitialize() is called.
