gem development, adding a file to auto-load

Hi all,

I've created a gem that allows you to describe menu systems for a
rails app (or engine). You can find it here; https://rubygems.org/gems/alacarte

I use a DSL thats similar to the routes file. I would like my file
(called alacarte.rb, which currently lives in config/initializers) to
auto-reload in development every time the file gets changed. Without
configuring the application every time (so it should be a setting/code
in the gem that makes it auto-reload).

Can someone point me in the direction on how to do this?

Thanks all!

Stijn
