Bintray For Plugins

This is currently in Beta mode.

sbt hosts their community plugin repository on Bintray. Bintray is a repository hosting site, similar to github, which allows users to contribute their own plugins, while sbt can aggregate them together in a common repository.

This document walks you through the means to create your own repository for hosting your sbt plugins and then linking them into the sbt shared repository. This will make your plugins available for all sbt users without additonal configuration (besides declaring a dependency on your plugin).
