Public Class ArgumentUsageAttribute
    Inherits Attribute

    ' This is the attribute constructor.
    Public Sub New(UsageMsg As String)
        Me.usageMsg = UsageMsg
    End Sub ' New

    ' usageMsg is storage for the attribute message.
    Protected usageMsg As String

    ' This is the Message property for the attribute.
    Public Property Message() As String
            Return usageMsg
        End Get
            usageMsg = value
        End Set
    End Property
