IMPORTANT update 2016: the plugin will not work correctly with Eclipse 3.5+ and the language libraries are woefully out of date.
Eclipse Plugin that provides a GUI for dynamic language interpreters. It's extensible (via the Plugin system), so it's easy to add support for new interpreters. Special support is available for Java based languages, like Beanshell etc.
Dead project, not keeping up with changes it seems. Doesn't pick up classpath as it claims, and code completion doesn't work as shown in the (sparse!) documentation. Wasted an hour trying to make it work...
