#!/bin/bash

USAGE="How to use:
runvidia [OPTION] <command>

Available OPTIONs:
--vsync            Sets vsync to turn ON, program-overridable
--vsync-force-off  Force vsync to OFF, regardless program's preferences
--primussync NUM   Changes primus_sync env var.
                   Defaults to NUM=1, which \"synchronizing primus' display
                   thread with the application's rendering thread\"
                   NUM=2 , \"display the latest rendered frame, trading frame 
                   rate for reduced visual latency\"
--optirun          Uses \"optirun\" instead of \"primusrun\", however
                   \"-b primus\" is still supplied to optirun
-h , --help        Print this help message

Anything not an option will be parsed as arguments to the subprogram!"
