+CMakeVerifyManifest.cmake
+
+This script is used to verify that embedded manifests and side by side
+manifests for a project match.  To run this script, cd to a directory
+and run the script with cmake -P.  On the command line you can pass in
+versions that are OK even if not found in the .manifest files.  For
+example, cmake -Dallow_versions=8.0.50608.0
+-PCmakeVerifyManifest.cmake could be used to allow an embedded manifest
+of 8.0.50608.0 to be used in a project even if that version was not
+found in the .manifest file.
+#]=======================================================================]
+
+# This script first recursively globs *.manifest files from
+# the current directory.  Then globs *.exe and *.dll.  Each
+# .exe and .dll is scanned for embedded manifests and the versions
+# of CRT are compared to those found in the .manifest files
+# from the first glob.
