FOSS gamedev and creative worlds

Sometimes i notice a application in the minetest bin folder called minetestserver iv'e tried clicking on it but it dosen't do anything is it to create a server or part of making a server. Could someone please tell me?

That is for starting a server. It should be run from the command line with the gameid specified, like "minetestserver --gameid minetest".

Oh thanks menche i was just curious about it.
