You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: options.rb
    path of file: ./repos/rdoc/lib/rdoc
    
    the code of the file until where you have to start completion: # frozen_string_literal: true
require 'optparse'
require 'pathname'

##
# RDoc::Options handles the parsing and storage of options
#
# == Saved Options
#
# You can save some options like the markup format in the
# <tt>.rdoc_options</tt> file in your gem.  The easiest way to do this is:
#
#   rdoc --markup tomdoc --write-options
#
# Which will automatically create the file and fill it with the options you
# specified.
#
# The following options will not be saved since they interfere with the user's
# preferences or with the normal operation of RDoc:
#
# * +--coverage-report+
# * +--dry-run+
# * +--encoding+
# * +--force-update+
# * +--format+
# * +--pipe+
# * +--quiet+
# * +--template+
# * +--verbose+
#
# == Custom Options
#
# Generators can hook into RDoc::Options to add generator-specific command
# line options.
#
# When <tt>--format</
