Using MongoHQ and central_logger on Heroku with rails app

Hi

I am trying to setup central_logger (GitHub - customink/central_logger: Ruby Mongo DB Logger for Rails - centralized logging for rails apps in MongoDB. Converted to gem, added global exception logging, and added Rails 3 (or 2) support.) to my heroku app. Can someone please point me to a tutorial or lay out steps on how I can achieve this? The readme is quite clear but doesn't say anything about heroku integration except for point 4 which says

For use with Heroku you need to prevent the rails_log_stdout plugin from being added by Heroku:

mkdir vendor/plugins/rails_log_stdout touch vendor/plugins/rails_log_stdout/.gitkeep

I dont quite understand this without some more context. It will be much appreciated.

APologies if the question is ambiguous.

Thanks! Satyam
