Twitterで特定の人のtweetにふぁぼテロする感じ。

favterro.rb

=begin

必要なもの
$ gem install rubytter
../oauth_yaml/#{Client}-#{App}.yaml ( TwitterOAuthの情報を格納したもの )
最初の方に定義してある定数をちょこちょこ書き換えるスキル

これはなに
指定した人の最新200件のtweetを取得して、既にふぁぼってるの以外をふぁぼります。
このscriptでふぁぼったものだけを #{@screen_name}-favterro-#{日付}.yaml に書き出すので、簡単にリセットできます。

つかいかた
ruby favterro.rb TARGET_Screen_name

戻し方
ruby favterro.rb (適当な単語) #{@screen_name}-favterro-#{日付}.yaml
