#options ⇒ Object
Actual Gem::OptionParser object, automatically created if nonexistent.
If called with a block, yields the Gem::OptionParser object and returns the result of the block. If an Gem::OptionParser::ParseError exception occurs in the block, it is rescued, a error message printed to STDERR and nil
returned.

#options=(opt) ⇒ Object
Sets Gem::OptionParser object, when opt
is false
or nil
, methods Gem::OptionParser::Arguable#options and Gem::OptionParser::Arguable#options= are undefined. Thus, there is no ways to access the Gem::OptionParser object via the receiver object.
