== Commands ==
:account {username}@{servicename}
    {servicename} に {username} でログインします．
    このとき，ログインマネージャーの値を使用するので，
    ログインマネージャーにパスワードを保存しておく必要があります．

:loginmultiaccounts
    .vimperatorrc であらかじめ設定しておいたアカウントすべてにログインします．
    日常的に使うサーヴィスのメインアカウントを登録しておくことで，コマンド一つで
    すべてにログインできます．


== Global variables ==
accountSwitcherServices
    Google, Hatena, Hatelabo 以外のアカウントにも対応することが出来ます．

accountSwitcherLoginServices
    :loginmultiaccounts でログインするアカウントの配列

== .vimperatorrc ==
以下の様に記述しておけば，:loginmultiaccounts を実行したときに
すべてのアカウントにログインできます．
>||
js <<EOM
liberator.globalVariables.accountSwitcherLoginServices = [
    'bar@hatena',
    'buz@hatelabo',
    'foo@google',
];
