I feel as if Eclipse is conspiring against me...
I have searched high and low help on creating "plug-in projects" and I have found TONS of useful resources. However, when I actually go to create my new plug-in project, the option is not there.
The instructions I have found usually say something like this:
Select "New Project" and choose "Plug-in Project".
I am on a Mac (10.5.6) running Eclipse (3.4.1). I also attached an image.
