# frozen_string_literal: true

# If this file is exist, RDoc generates and removes documents by rubygems plugins.
#
# In follwing cases,
# RubyGems directly exectute RDoc::RubygemsHook.generation_hook and RDoc::RubygemsHook#remove to generate and remove documents.
#
# - RDoc is used as a default gem.
# - RDoc is a old version that doesn't have rubygems_plugin.rb.

# At that time, rdoc/markdown is not generated.
# If generate and remove are executed at that time, an error will occur.
# So, we can't register generate and remove to Gem at that time.
