Hello,  
I wrote a plugin that adds some rake tasks. Upon installation of my  
plugin, I would like one of these rake tasks to be run. How do I do  
that in install.rb?

Thank you.

Rake::Task[‘task:name’].invoke

I tried that and then ‘script/plugin install’ wouldn’t install it  
cleanly anymore.

When a plugin is installed, how/when is the install.rb file invoked?  
I mean, in that file, can I count on the Rails environment already  
being loaded?

Also, how do I test that file? I can’t simply say “ruby install.rb”  
unless I load all the environment stuff myself in that file.

Thanks for the help.
