-# frozen_string_literal: true
-# Profile provides a way to Profile your Ruby application.
-#
-# Profiling your program is a way of determining which methods are called and
-# how long each method takes to complete. This way you can detect which
-# methods are possible bottlenecks.
-#
-# Profiling your program will slow down your execution time considerably,
-# so activate it only when you need it. Don't confuse benchmarking with
-# profiling.
-#
-# There are two ways to activate Profiling:
-#
-# == Command line
-#
-# Run your Ruby script with <code>-rprofile</code>:
-#
-# ruby -rprofile example.rb
-#
-# If you're profiling an executable in your <code>$PATH</code> you can use
-# <code>ruby -S</code>:
-#
-# ruby -rprofile -S some_executable
-#
-# == From code
-#
-# Just require 'profile':
-#
-# require 'profile'
-#
-# def slow_method
-# 5000.times do
-# 9999999999999999*999999999
-# end
-# end
-#
-# def fast_method
-# 5000.times do
-# 9999999999999999+999999999
-# end
-# end
-#
-# slow_method
-# fast_method
-#
-# The output in both cases is a report when the execution is over:
