+# this is NOT the file you are looking for. Do NOT directly modify this file. Any change should
+# first be done in the https://github.com/enterprise-contract/ec-cli repository then synced to this
+# repository. Any pull request that modifies anything other than this comment in this file and is
+# not a sync from the ec-cli repository will be immediately closed. See
