function Export-DbaRepServerSetting {
    <#
        .SYNOPSIS
            Exports replication server settings to file.
 
        .DESCRIPTION
            Exports replication server settings to file.
 
        .PARAMETER SqlInstance
            The target SQL Server instance or instances
 
        .PARAMETER SqlCredential
            Login to the target instance using alternative credentials. Windows and SQL Authentication supported. Accepts credential objects (Get-Credential)
 
        .PARAMETER Path
            Specifies the path to a file which will contain the output.
 
        .PARAMETER Passthru
            Output script to console
         
        .PARAMETER NoClobber
            Do not overwrite file
 
        .PARAMETER Encoding
            Specifies the file encoding. The default is UTF8.
 
            Valid values are:
            -- ASCII: Uses the encoding for the ASCII (7-bit) character set.
            -- BigEndianUnicode: Encodes in UTF-16 format using the big-endian byte order.
            -- Byte: Encodes a set of characters into a sequence of bytes.
            -- String: Uses the encoding type for a string.
            -- Unicode: Encodes in UTF-16 format using the little-endian byte order.
            -- UTF7: Encodes in UTF-7 format.
            -- UTF8: Encodes in UTF-8 format.
            -- Unknown: The encoding type is unknown or invalid. The data can be treated as binary.
 
        .PARAMETER Append
            Append to file
     
        .PARAMETER ScriptOption
            Not real sure how to use this yet
 
        .PARAMETER InputObject
            Allows piping from Get-DbaRepServer
 
        .PARAMETER EnableException
            By default, when something goes wrong we try to catch it, interpret it and give you a friendly warning message.
            This avoids overwhelming you with "sea of red" exceptions, but is inconvenient because it basically disables advanced scripting.
            Using this switch turns this "nice by default" feature off and enables you to catch exceptions with your own try/catch.
