const (
	ExitUnknownError   = 1 // for compatibility with existing exit code
	ExitIncorrectUsage = 64
	ExitDataError      = 65 // some format error with input data

	// below here are non-zero exit codes that don't indicate an error with istioctl itself
	ExitAnalyzerFoundIssues = 79 // istioctl analyze found issues, for CI/CD
)

Values should try to use sendmail-style values as in <sysexits.h> See e.g. https://man.openbsd.org/sysexits.3 or `less /usr/includes/sysexits.h` if you're on Linux

Picking the right range is tricky--there are a lot of reserved ones (see https://www.tldp.org/LDP/abs/html/exitcodes.html#EXITCODESREF) and then some used by convention (see sysexits).

The intention here is to use 64-78 in a way that matches the attempt in sysexits to signify some error running istioctl, and use 79-125 as custom error codes for other info that we'd like to use to pass info on.
