VGHTC Wireless Auto-login for Mac OS X

每次筆電從休眠狀態復原，連上網路後，總要重新輸入 web authentication，用鍵盤輸入是不用花多少時間，但在智慧型手機上就很令人厭煩，於是先找了一個 WLanLogin 的 App，找出 VGHTC 的登入網址和參數，測試成功後，果然方便許多。回過頭來想，如果筆電也能自動登入，那不也很方便嗎？所以參考了這篇 For NTNU 的設定，修改為 VGHTC 的版本：

環境： Mac OS X 10.6.8

設定 LaunchAgent

~/Library/LaunchAgents/LocationChanger.plist
