Установка флагов

; This file will store the commands used by plugins, and their access level
; To change the access of a command, edit the flags beside it and then
; change the server's map.
;
; Example: If I wanted to change the amx_slap access to require
; RCON access (flag "l") I would change this:
; "amx_slap" "e" ; admincmd.amxx
; To this:
; "amx_slap" "l" ; admincmd.amxx
;
; To disable a specific command from being used with the command manager
; and to only use the plugin-specified access set the flag to "!"
;
; NOTE: The plugin name at the end is just for reference to what plugin
; uses what commands. It is ignored.

"amx_statscfgmenu" "h" ; statscfg.amxx
"amx_statscfg" "h" ; statscfg.amxx
"amx_reloadadmins" "h" ; admin.amxx
