class DistutilsOptionError(DistutilsError): (source)
Syntactic/semantic errors in command options, such as use of mutually conflicting options, or inconsistent options, badly-spelled values, etc. No distinction is made between option values originating in the setup script, the command line, config files, or what-have-you -- but if we *know* something originated in the setup script, we'll raise DistutilsSetupError instead.
