[F I]

hi.
I can not load admin plugin.
Mysql Proxy: mysql-proxy-0.8.2-win32-x86.zip, binary installed.
Mysql Server: 5.1.60

cmd:
C:\Users\Administrator>mysql-proxy --admin-lua-script=d:/mysql-proxy/admin.lua -
-admin-username=root --admin-password=password --proxy-backend-addresses=127.0.0
.1:3306 --proxy-lua-script=reporter.lua
2012-03-06 16:44:28: (critical) .\mysql-proxy-cli.c:501: Unknown option --admin-
lua-script=d:/mysql-proxy/admin.lua (use --help to show all options)

Thanks.
