Installing a Plugin from a Local Directory

I am working on writing a simple plugin basically just to understand how to do it. My whole project is in svn and I did a script/generate plugin. I added a module in lib and a .js that needs to be moved to public. I have figured out enough from the tutorials how to get that script to copy over with install.rb and how to get the mixin added with init.rb. What I haven’t been able to do is simulate the installation of it (since my repo is ssl and password protected). Any ideas?
