Hello, I'm callmekohei!

Problem

I want to display app's stdout in sdb plugin.

code

open Mono.Debugger.Client
open Mono.Debugging.Client

open System.IO

[<Sealed; Command>]
type MyCommand() =
    inherit Command()
    override __.Names   = [|"mycmd"|]
    override __.Summary = "aaa bbb ccc"
    override __.Syntax  = "ddd eee fff"
    override __.Help    = "Help Help Help"
    override __.Process(args) =

    Log.Info("-----------------")

    /// I want to display app's stdout!
    ????

    Log.Info("-----------------")

I'm happy to have a tip (^_^)/
