class Byebug::EnableDisableCommand

def description
  prettify <<-EOD
    (en|dis)[able][[ (breakpoints|display)][ n1[ n2[ ...[ nn]]]]]
     Enables or disables breakpoints or displays.
     "enable" by itself enables all breakpoints, just like
     "enable breakpoints". On the other side, "disable" or
     "disable breakpoints" disable all breakpoints.
     You can also specify a space separated list of breakpoint numbers to
     enable or disable specific breakpoints. You can use either
     "enable <id1> ... <idn>" or "enable breakpoints <id1> ... <idn>" and
     the same with "disable".
     If instead of "breakpoints" you specify "display", the command will
     work exactly the same way, but displays will get enabled/disabled
     instead of breakpoints.
