+            Sometimes we don't just want to overwrite the existing kobo file; instead we need to merge them.
+            This is the executable which does this.
+            The first argument is the local file and the second is the kobo file.
+            Note that the local file path and the kobo file path only disagree in their top-level directory and otherwise are the same path.

+            In general, the manifest only considers local files that match the target/pattern.
+            Setting this to true means that the kobo files will be scanned and the provided mergeTool will be run with the first argument set to null.
