/* RetroLogger.scala | |
* | |
* A handy sbt-0.10.x plugin that allows you to set the log level like in the | |
* old days (AKA sbt-0.7.x). | |
* | |
* It works by creating aliases of this form: | |
* "set logLevel := Level.Debug" ====> "debug" | |
* | |
* Installation: | |
* - mkdir -p ~/.sbt/plugins/ | |
* - cp path/to/RetroLogger.scala ~/.sbt/plugins/ | |
* - touch ~/.sbt/plugins/build.sbt | |
* - add "sbtPlugin := true" to ~/.sbt/plugins/build.sbt | |
* | |
* Author: Gerolf Seitz | |
