Make sure all the options to replay are shown in the short option list without descriptions in USAGEmd, in the extended list with descriptions in USAGEmd, and in the --help output in tools/replay/replay_settings.h .
An example of one that is inconsistent is --quit-after-frame. It's not listed in the short option list nor the --help output.
Go through them all and make sure they are consistent through documentation, including options that are API-specific.
