-// This class works with command lines: building and parsing.
-// Arguments with prefixes ('--', '-', and on Windows, '/') are switches.
-// Switches will precede all other arguments without switch prefixes.
-// Switches can optionally have values, delimited by '=', e.g., "-switch=value".
-// An argument of "--" will terminate switch parsing during initialization,
-// interpreting subsequent tokens as non-switch arguments, regardless of prefix.
-
-// There is a singleton read-only CommandLine that represents the command line
-// that the current process was started with.  It must be initialized in main().
