                                function Remove-DbaCmConnection {

    <#

    .SYNOPSIS

        Removes connection objects from the connection cache used for remote computer management.

    .DESCRIPTION

        Removes connection objects from the connection cache used for remote computer management.

    .PARAMETER ComputerName

        The target computer. Accepts both text as well as the output of Get-DbaCmConnection.

    .PARAMETER WhatIf

        If this switch is enabled, no actions are performed but informational messages will be displayed that explain what would happen if the command were to run.

    .PARAMETER Confirm

        If this switch is enabled, you will be prompted for confirmation before executing any operations that change state.

    .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.
