function Get-DbaReportingService {
    <#
    .SYNOPSIS
        Gets the SQL Server Reporting Services on a computer.
 
    .DESCRIPTION
        Gets the SQL Server Reporting Services on one or more computers.
 
        Requires Local Admin rights on destination computer(s).
 
    .PARAMETER ComputerName
        The target SQL Server instance or instances.
 
    .PARAMETER InstanceName
        Only returns services that belong to the specific instances.
 
    .PARAMETER Credential
        Credential object used to connect to the computer as a different user.
 
    .PARAMETER ServiceName
        Can be used to specify service names explicitly, without looking for service types/instances.
 
    .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.

    .EXAMPLE
        PS C:\> Get-DbaReportingService -ComputerName sqlserver2014a
 
        Gets the Reporting Services on computer sqlserver2014a.
 
    .EXAMPLE
        PS C:\> $cred = Get-Credential WindowsUser
        PS C:\> Get-DbaReportingService -ComputerName sql1,sql2 -Credential $cred | Out-GridView
 
        Gets the Reporting Services on computers sql1 and sql2 via the user WindowsUser, and shows them in a grid view.
