+<!-- Aegis manifest declares the security credentials required by an
+     application to run correctly. By default, a manifest file will be
+     created or updated automatically as a part of build.
+
+     The detection of required credentials is based on static scan of
+     application binaries. In some cases, the scan may not be able to
+     detect the correct set of permissions. If this is the case, you must
+     declare the credentials required by your application in this file.
+
+     To create a manifest file automatically as a part of build (DEFAULT):
+
+      * You may leave this file as-is.
+      * Do not list any '<credential name="token" />' entries
+        outside of comments.
+
+     To provide a manifest yourself:
+
+      * List the correct credentials for the application in this file.
+      * Some commented-out examples of often required tokens are provided.
+      * Ensure the path to your application binary given in
+        '<for path="/path/to/app" />' is correct.
+      * Please do not request more credentials than what your application
+        actually requires.
+
+     To disable manifest file:
+
+      * Replace this file with a file starting with the string "NoAegisFile" (without quotes).
+      * Final application package will not contain a manifest.
