What does bundle install --binstubs serve for us?

Question

When do you execute the following command? Also, do you explain what it gives for us?

$ bundle install --binstubs

Answer 1

From bundle install --help man page

--binstubs[=<directory>]
              Creates a directory (defaults to ~/bin) and place any executables from the gem there. These executables run in Bundler's context. If used, you might add this directory to your
              environment's PATH variable. For instance, if the rails gem comes with a rails executable, this flag will create a bin/rails executable that ensures that all  referred  depen-
              dencies will be resolved using the bundled gems.
