Rails guide should explain using rails binstubs

[indirect]

In the Rails guide, we ask users to run bundle exec rails new, which makes sense if you need to generate a Rails app from a specific version of Rails—after the Rails app is generated, though, users should run bin/rails rather than bundle exec rails. Let's document that.

@indirect Not exactly sure where in the existing Rails guides (2.3 or 3) this would come into play as I don't see anywhere that we currently ask users to use bundle exec rails new?

@RochesterinNYC ah, sorry, I must have been thinking of something else I have written explaining how to create rails apps using a specific version of rails. If the rails guide explains how the rails gem works, maybe that can reduce confusion around this.

Dear Bundler people.

I was just about to find the docs about binstubs.

http://bundler.io/v1.14/man/bundle-binstubs.1.html refers to them, but does not define what they are (they're scripts that launch Ruby executable programs offered by Rubygems).

Mislav's text about them in the rbenv wiki is quite great: https://github.com/rbenv/rbenv/wiki/Understanding-binstubs

This repository does not have much text about them https://github.com/bundler/bundler-site/search?utf8=%E2%9C%93&q=binstub Should it?
