This link has been broken since at least Ruby 3.0. The `OptionParser#on` method documentation has a [broken link](https://ruby-doc.org/3.4.1/stdlibs/optparse/OptionParser.html#method-i-on) for the text [Parameters for New Options](https://ruby-doc.org/3.4.1/stdlibs/optparse/optparse/option_params_rdoc.html). The desired target document is here: https://ruby-doc.org/3.4.1/optparse/option_params_rdoc.html The broken link should be corrected. Also, the sample program for https://ruby-doc.org/3.4.1/optparse/option_params_rdoc.html#label-Simple+Long+Names has code that needs to be encapsulated within <pre></pre>.
