Overview

We include a module here so you can define your own help

command and call #super to utilize this one.

module Help

def help
  opts = help_options
  s = ""
  s << "#{File.basename($0)}\n\n"
  unless opts.empty?
    s << "OPTIONS\n"
    s << help_options
    s << "\n"
  end
  s << "COMMANDS\n"
  s << help_commands
  puts s
end

  help = self.class.help
  bufs = help.keys.collect{ |a| a.to_s.size }.max + 3
  lines = []
  help.each { |cmd, str|
    cmd = cmd.to_s
    if cmd !~ /^_/
      lines << "  " + cmd + (" " * (bufs - cmd.size)) + str
    end
  }
  lines.join("\n")
end

def help_options
  help = self.class.help
  bufs = help.keys.collect{ |a| a.to_s.size }.max + 3
