This include lets you create more than one checkpoint at the same time!(Requires Incognito's Streamer)
P.S: If your server's player base is using the android client this will NOT work for them and will probably make their game crash.
Just copy and paste Cps.inc into your pawno/include folder and use #include <Cps.inc> in your script after including a_samp and streamer, then use the functions provided to create and manage your checkpoints.
