+/*
+ * ==VimperatorPlugin==
+ * @name toggler
+ * @version 0.1
+ * @author teramako <teramako at gmail.com>
+ * ==/VimperatorPlugin==
+ *
+ * 何かしらの設定をクルクル変更したい人へ
+ * 
+ * まず、最初に以下の例ように.vimperatorrcに定義する
+js <<EOM
+liberator.globalVariables.toggler = [
+  ["name",[ setting commands ]],
+  ["go",["set go=","set go=m","set go=b"]],
+  ["sb",["sbclose","sbar Console"]]
+  ["go_and_sb", [["set go=","sbclose"],["set go=mTb","sbar Console"]]]
+  ...
+];
+EOM
+ * 
+ * 次に
+ * :toggle go
+ * とコマンドを実行するとsetting commands配列の次を実行する
+ * 最後までいくと最初に戻る
+ * つまり、最初に :toggle go をすると set go=m が実行される
+ * もう一度実行すると、set go=b が実行される
+ * もう一度すると、最初に戻って、set go= が実行される
+ *
+ * :map <F2> :toggle go<CR>
+ * などとやっておくとボタン一つでクルクル替わる
