// values to any defined Abseil flags. (Any arguments passed after the

// flag-terminating delimiter (`--`) are treated as positional arguments and
|
|
// ignored.)

|

// Flag values, if those flags are defined. Any undefined flags will either

// return an error, or be ignored if that flag is designated using `undefok` to
|
|
// indicate "undefined is OK."

// arguments to a flag) are returned in a vector, with the program invocation

// name at position 0 of that vector. (Note that this includes positional
|
|
// arguments after the flag-terminating delimiter `--`.)

// After all flags and flag arguments are parsed, this function looks for any

|
// built-in usage flags (e.g. `--help`), and if any were specified, it reports

// help messages and then exits the program.
