function SQL-Get-Server-Instance 
{ 
    <# 
    .SYNOPSIS 
    Returns the proper instance name based on the values specified either in the script 
    config file, or the default values provided in the PowerShell profile file. 

    .DESCRIPTION 
    This is basically a utility function called by other functions for covering the case 
    where the default instance is used (MSSQLSERVER). When the default instance is used, 
    SQL-Get-Server-Instance will only return the server name. 

    .PARAMETER DatabaseServer 
    The database server to be used (default: $global:DatabaseServer). 

    .PARAMETER InstanceName 
    The instance name to be used (default: $global:InstanceName). 

    .EXAMPLE 
    SQL-Get-Server-Instance 
    #> 

    param (
     [parameter(Mandatory = $false)][string] $DatabaseServer = $global:DatabaseServer, 
     [parameter(Mandatory = $false)][string] $InstanceName = $global:InstanceName 
    ) 

    if (!$InstanceName -or $InstanceName -eq "" -or $InstanceName -eq "MSSQLSERVER") 
     { return $DatabaseServer } 
    else 
     { return "$DatabaseServer\$InstanceName" } 
} 


function SQL-Script-Database 
{ 
    <# 
    .SYNOPSIS 
    Script all database objects for the given database. 

    .DESCRIPTION 
    This function scripts all database objects (i.e.: tables, views, stored 
    procedures, and user defined functions) for the specified database on the 
    the given server\instance. It creates a subdirectory per object type under 
    the path specified. 

    .PARAMETER savePath 
    The root path where to save object definitions. 

    .PARAMETER database 
    The database to script (default = $global:DatabaseName) 

    .PARAMETER DatabaseServer 
    The database server to be used (default: $global:DatabaseServer). 

    .PARAMETER InstanceName 
    The instance name to be used (default: $global:InstanceName). 

    .EXAMPLE 
    SQL-Script-Database c:\temp AOIDB 
    #> 

    param (
     [parameter(Mandatory = $true)][string] $savePath, 
     [parameter(Mandatory = $false)][string] $database = $global:DatabaseName,
