AutoSPSourceBuilder.ps1

<#
.SYNOPSIS
    Builds a SharePoint 2010/2013/2016 Service Pack + Cumulative Update slipstreamed installation source.
.DESCRIPTION
    Starting from existing (user-provided) SharePoint 2010/2013/2016 installation media/files (and optionally Office Web Apps / Online Server media/files),
    the script can download the prerequisites, specified Service Pack and CU/PU packages for SharePoint/WAC, along with specified (optional) language packs, then extract them to a destination path structure.
    Uses the AutoSPSourceBuilder.XML file as the source of product information (URLs, builds, naming, etc.) and requires it to be present in the same folder as the AutoSPSourceBuilder.ps1 script.
.EXAMPLE
    AutoSPSourceBuilder.ps1 -UpdateLocation "C:\Users\brianl\Downloads\SP" -Destination "D:\SP\2010"
.EXAMPLE
    AutoSPSourceBuilder.ps1 -SourceLocation E: -Destination "C:\Source\SP\2010" -CumulativeUpdate "December 2011" -Languages fr-fr,es-es
.PARAMETER SourceLocation
    The location (path, drive letter, etc.) where the SharePoint binary files are located.
    You can specify a UNC path (\\server\share\SP\2010), a drive letter (E:) or a local/mapped folder (Z:\SP\2010).
    If you don't provide a value, the script will check every possible drive letter for a mounted DVD/ISO.
.PARAMETER Destination
    The file path for the final slipstreamed SP2010/SP2013/2016 installation files.
    The default value is $env:SystemDrive\SP\2010 (so in most cases, C:\SP\2010).
.PARAMETER UpdateLocation
    The file path where the downloaded service pack and cumulative update files are located, or where they should be saved in case they need to be downloaded.
    The default value is the subfolder <Destination>\Updates (so, typically C:\SP\201x\Updates).
.PARAMETER GetPrerequisites
    Specifies whether to attempt to download all prerequisite files for the selected product, which can be subsequently used to perform an offline installation.
    The default value is $false.
.PARAMETER CumulativeUpdate
    The name of the cumulative update (CU) you'd like to integrate.
    The format should be e.g. "December 2011".
    If no value is provided, the script will prompt for a valid CU name.
.PARAMETER WACSourceLocation
    The location (path, drive letter, etc.) where the Office Web Apps / Online Server binary files are located.
    You can specify a UNC path (\\server\share\SP\2010), a drive letter (E:) or a local/mapped folder (Z:\WAC).
    If no value is provided, the script will simply skip the WAC integration altogether.
.PARAMETER Languages
    A comma-separated list of languages (in the culture ID format, e.g. de-de,fr-fr) used to specify which language packs to download.
    If no languages are provided, the script will simply skip language pack integration altogether.
