// SoundCloud から Tumblr に audio ポストする tombloo パッチ
// SoundCloud へリンクするタイプの Audio ポストができる
// 音声ファイルつきの Audio ポストにはならない
////////////////////////////////////////////////////////////////

// ポストするとき tombloo の小窓にタイトル等が表示されない.
// quickPostForm.js を編集すると表示できるけど
// パッチからいじる方法がわからないのでそのまま.

// 他のポストタイプを真似して audio ポストタイプを作る
