Usage Notes:

• Option characters are not case sensitive: /R and /r are equivalent.
  
• Options can be shortened to the fewest characters that uniquely identify them. The characters in brackets can be omitted: /N and /NOLOGO are equivalent.
  
• Although use of the minimum one-letter abbreviations is allowed, if a future release has an additional option starting with the same letter, the one-letter option will no longer be usable.
