I wrote a tool in ruby which I want to put entirely in a gem.  The tool, 
however, requires a directory of plugins and a config file, which the 
tool should ideally be able to find in default locations.

I can include the plugin and config directories in the GemSpec without 
any trouble, but when the tool is run, it needs to be able to find them.

The only way I could figure out to do this was to hard-code this into 
the tool:

def where_am_i?
   "#{Gem.path}/gems/tool-#{VERSION}"
end

And append the plugin and config paths to it.  Surely there's a better 
way to do all of this. Suggestions?
