for debug
Mark a command-line option as deprecated, and optionally specify a deprecation horizon.
Note that with the current implementation, every version of the option needs to be explicitly deprecated, so to deprecate an option defined as
add_option('-t', '--[no-]test', 'Set test mode') do |value, options| # ... stuff ... end
you would need to explicitly add a call to ‘deprecate_option` for every version of the option you want to deprecate, like
deprecate_option('-t') deprecate_option('--test') deprecate_option('--no-test')
Merge a set of command options with the set of default options (without modifying the default option hash).
Handle the command arguments.
