class OptionParser::Switch::RequiredArgument

Customize OptionParser RequiredArgument switch class to support multi character short switches (single ‘-’ prefix) with (optional) arguments. These must be defined using a format like ‘-X<text>’ or ‘-X{text}’ where ‘X’ is the common start character for a group of short multichar switches. Switch arguments should be indicated by either appending ‘=ARG’ or ‘ ARG’ giving something like ‘-X<text>=ARG’ or ‘-X<text> ARG’ where ‘ARG’ is an arbitrary non-blank text
