    # == Synopsis
    #
    #   URI::Parser.new([opts])

    # == Args
    #
    # The constructor accepts a hash as options for parser.
    # Keys of options are pattern names of URI components
    # and values of options are pattern strings.
    # The constructor generates set of regexps for parsing URIs.
    #
    # You can use the following keys:
    #
    #   * :ESCAPED (URI::PATTERN::ESCAPED in default)
    #   * :UNRESERVED (URI::PATTERN::UNRESERVED in default)
    #   * :DOMLABEL (URI::PATTERN::DOMLABEL in default)
    #   * :TOPLABEL (URI::PATTERN::TOPLABEL in default)
    #   * :HOSTNAME (URI::PATTERN::HOSTNAME in default)
    #
    # == Examples
    #
    #   p = URI::Parser.new(:ESCAPED => "(?:%[a-fA-F0-9]{2}|%u[a-fA-F0-9]{4})")
    #   u = p.parse("http://example.jp/%uABCD") #=> #<URI::HTTP http://example.jp/%uABCD>
