+            This is an automatically generated pull request.
+
+            This pull request compiles all the scripts in the `Update` folder into the `CompiledUpdateScripts` folder,
+            so the end-user does not need to compile it on their end.
+
+            You should accept this pull request just before releasing a patch. Please do not accept this pull request at other times,
+            as this will generate unnecessary commits.
