Useful sbt commands:

# download all sources & javadoc of jars.如果需要为导入到 eclipse 中的 scala 项目的依赖 jars 自动关联 srcs，请在项目的 build.sbt 文件中添加（参见 http://stackoverflow.com/questions/10472840/how-to-attach-sources-to-sbt-managed-dependencies-in-scala-ide）：
# EclipseKeys.withSource := true
$ sbt update-classifiers
# 使用 sbteclipse 时，terminal 下(http://stackoverflow.com/questions/13803459/how-to-use-sbt-from-behind-proxy)：
$ export SBT_OPTS="$SBT_OPTS -Dhttp.proxyHost=127.0.0.1 -Dhttp.proxyPort=8087"

Concurrency in Scala:
Two concurrency implementations in Scala:

thread-based concurrency (or shared-state concurrency): derived from Java
Actor-based concurrency (actor concurrency model): inspired by Erlang.
