+WDKBatchBuild
+
+JakobL@2025/11/19
+
+Build this repo in "batch mode" using multiple EWDKs. 
+
+Once batch build is complete you will find complete copies of built repo with generated artifacts ready for your favorite diff algorithm.
+
+Files:
+* WDKBatchBuild.ps1 <-- Main script. Change bottom part to refine functionality.
+* WDKBatchBuild_Internal.ps1. Auxillary function.
+
+Tricks:
+* Nifty lazy ISO file copy.  Only copies if necessary.
+* Nifty lazy ISO extraction.  Caches EWDKs.  Only extracts what is necessary.
+* Nifty trick to invoke build environment and build:
+  * Does following N times:
+    * Starts out in main PowerShell script
+    * Calls cmd script EWDK\BuildEnv\SetupBuildEnv.cmd to setup build environment
+    * Continuation into auxillary PowerShell script
+
+Warning:
+* Will run "clean -xdf" in root of repo thereby wiping out anything not checked in.
+* Make sure to check changes to this script in before running.
+
+Assumptions:
+* Requires new pwsh (rather than old powershell).
+* Hard coded in script WDKBatchBuild.ps1:
+  * Repo in D:\wds\wds1
+  * Input ISOs in D:\wds\ISOs
+  * Temporary EWDKs extracted to D:\wds\EWDKs
+  * Output runs in D:\wds\Runs
