easyb now has an Eclipse plugin -- this is a work in progress, however, early versions support running easyb stories and specifications and support an Outline view of behaviors. What's more, there is a behavior creation wizard and various templates available in the Eclipse Preferences view. By right clicking on a .story file (or .specification) you can select the Run As item, and then you'll see a handy option to run as an easyb story.

Installing the plug-in works as follows:

1. Go to the Help menu and then select Software Updates...
2. Hit the Add Site.. button and in the resulting dialog, for the location type: http://easyb.googlecode.com/svn/trunk/eclipse-plugins/org.easyb.eclipse.updatesite/
3. Hit the Ok button
4. Select the easyb Eclipse Update Site in the list box and then hit the Install... button

That's it!
