def self.hash(argv = ARGV.dup, values = [])
  @hash ||= begin
    argv.shift until argv.first =~ HASHER_REGEX or argv.empty?
    while argv.first =~ HASHER_REGEX and argv.size >= 2 do
      values += [argv.shift.sub(/^--?/, ''), argv.shift]
    end
    Hash[*values]
  end
end

.reset_hash! ⇒ Object

Clear the cached hash value. Probably only useful for tests, but whatever.
