def options
  @options ||= self.class.build_options(self)
end

#parse_options(argv, sep_support = :none) ⇒ Object

Parses options in ‘argv` with an OptionParser instance and returns non-options arguments.

The following example illustrates the role of ‘sep_support`

parse_options %w{--verbose hello -- quickl --say and world}
# => ["hello", "quickl", "--say", "and", "world"]

parse_options %w{--verbose hello -- quickl --say and world}, :keep
# => ["hello", "--", "quickl", "--say", "and", "world"]

parse_options %w{--verbose hello -- quickl --say and world}, :split
# => [["hello"], ["quickl", "--say", and", "world"]]
