Binstubs, short for “binary stubs,” are small executable scripts that act as wrappers around Ruby executables or scripts. They are commonly used in Ruby projects managed with Bundler to provide a convenient way to execute commands without needing to prepend them with bundle exec.

When you run `bundle install –binstubs` Bundler will create a bin folder full of any executables that your gems are capable of.

When I ran `bundle install –binstubs` on the jekyll project for this website I got results of:

% bundle install --binstubs

[DEPRECATED] The --binstubs option will be removed in favor of `bundle binstubs --all`
