Update application's crontab entries using Whenever. You can configure \
the command used to invoke Whenever by setting the :whenever_command \
variable, which can be used with Bundler to set the command to \
"bundle exec whenever". You can configure the identifier used by setting \
the :whenever_identifier variable, which defaults to the same value configured \
for the :application variable. You can configure the environment by setting \
the :whenever_environment variable, which defaults to the same value \
configured for the :rails_env variable which itself defaults to "production". \
Finally, you can completely override all arguments to the Whenever command \
by setting the :whenever_update_flags variable.
