This automation add-on will install user specified gems and make them available on the library search path.
Gem versions may be specified using the standard ruby gem_name=version format.
The version number follows the [pessimistic version constraint](https://guides.rubygems.org/patterns/#pessimistic-version-constraint) syntax.
Multiple version specifiers can be added by separating them with a semicolon.
For example this configuration will install the latest version of the [openHAB JRuby Scripting Library](https://boc-tothefuture.github.io/openhab-jruby/), and instruct the scripting engine to automatically insert `require 'openhab'` at the start of the script.

When this add-on is installed, you can select JRuby as a scripting language when creating a script action within the rule editor of the UI.
