==> Caveats
You can use $SBT_OPTS to pass additional JVM options to SBT.
For convenience, this can specified in `~/.sbtconfig`.

For example:
    SBT_OPTS="-XX:+CMSClassUnloadingEnabled -XX:MaxPermSize=256M"

sbtって何？

みんなマクロマクロってカツオの仲間？

http://docs.scala-lang.org/ja/overviews/macros/overview.html

なるほどわからん

[20:41:01]otiai10 % mkdir ~/prj/scala
[20:41:04]otiai10 % cd prj/scala
[20:44:07]otiai10 % vi Hello.scala

Hello.scala

object Hello {
  def main(arg: Array[String]) = {
    println("Hello, Tainaka Ritsu!!")
  }
}

で、ビルドしようとすると
