Actually, they mostly use the LUA mod, available from http://sveark.info/ac/lua (although I think the site is down right now)
You can find the GEMA script on the download page, although it doesn't come with !gtop and !grank by default. You can probably find someone to give you the code for it (or write it yourself, if you have that knowledge).
Note: You MUST remove the !jump and !nade commands, otherwise your server could be blacklisted for illegal mods.
