wxPython PyCrust simplest way I found to optionally add this in when needed

pycrust-example-main.py

PYCRUST = True  

if __name__ == "__main__":
    app = wx.App()
    wx.Log.SetActiveTarget(wx.LogStderr())

    # Top-level reference to my Frame
    fr = myFrame()
    fr.Show()

    # inspect the running wxPython app in
    # separate frame when PYCRUST is True
    if PYCRUST==True:
        from wx.py.crust import CrustFrame
        crust = CrustFrame(None)
        crust.Show()

    app.MainLoop()
