Watchr – More Than An Automated Test Runner

@shimizukawa ご紹介ありがとうございます！このへんは使いやすくて高機能なものを選ぶべきでしょうね(Rubyだったらwatchrよりguardを使うひともいるかも．http://t.co/gzUkPVsg に比較感想が少しあります)．

Watchr works by allowing you to specify the path to the file or files you want to monitor. When the file is changed it executes whatever block of Ruby code you give it. As the README states its most common use case is as a replacement for autotest. After using Watchr for a couple years now, I have learned that it’s much more than that. For example, it has helped me automatically copy a setup script to a virtual machine while building it and to update large blocks of content in a database.
