Installing a Plugin from a Local Directory

I am working on writing a simple plugin basically just to understand how
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
with install.rb and how to get the mixin added with init.rb. What I
been able to do is simulate the installation of it (since my repo is ssl
password protected). Any ideas?
