If you actually read the documentation (it's right at the top) you knew 
that this is not possible:
"There are many different syntaxes for options; the traditional Unix 
syntax is a hyphen (“-“) followed by a single letter [...] The GNU 
project introduced "--" [...] These are the only two option syntaxes 
provided by optparse.
Some other option syntaxes that the world has seen include:
[...]
a slash followed by a letter, or a few letters, or a word, e.g. "/f", 
"/file"

These option syntaxes are not supported by optparse, and they never will 
be. This is deliberate: [...] the last only makes sense if you’re 
exclusively targeting VMS, MS-DOS, and/or Windows."
